NETW208 Week7 Final Project - WIDGET CORPORATION

Overview

Widget Corporation is a leading architectural firm headquartered in Toronto, Canada, with a global presence. The company employs approximately 300 people across 10 sites, ranging from a single part-time person in a small office/home office (SOHO) to 150 regular office staff. The headquarters houses four major departments: Design, Human Resources, Marketing, and Sales. Given the increasing demand for the companyā€™s products, there is a critical need to tighten the integration of its customers and partners into the information infrastructure. This expansion and upgrade of the network are vital to maintaining Widget Corporationā€™s position as an industry leader.

Current Situation

The current network setup of Widget Corporation lacks the necessary redundancy and backup mechanisms, which could lead to significant operational issues in the event of a network failure. The absence of a robust IP addressing scheme also hampers scalability, making it difficult to manage and expand the network efficiently.

  1. Redundancy: The lack of redundancy in the network is a major concern. Redundancy involves having multiple pathways or backups for power and communication within the network. Without redundancy, a single point of failure can disrupt the entire network, leading to downtime and potential data loss.
  2. IP Addressing: The existing IP addressing scheme is inefficient and not scalable. This limitation could pose a challenge as the company continues to expand. An optimized IP addressing scheme is essential for reducing routing table complexity and improving overall network performance.
  3. Scalability and Security: The company aims to expand its market presence, which requires a scalable and secure network infrastructure. The current setup does not adequately separate the four departments, which could lead to data security concerns. Implementing VLANs and deploying security policies will be crucial in addressing these issues.

Headquarters Campus Redesign

The proposed redesign focuses on maintaining the current Cisco 6500 Catalyst Switches while implementing Ether-channels on its interfaces. Ether-channel is a technology that allows multiple physical Ethernet links to be combined into one logical link for increased bandwidth and redundancy. This setup will enable fast switching capabilities, which is crucial for the user experience.

  1. Implementation of VLANs: VLANs (Virtual Local Area Networks) will be implemented to separate the four departments within the headquarters. VLANs improve network security by segmenting traffic, ensuring that data flows only within designated segments. This segmentation reduces the risk of data breaches and improves overall network efficiency.
  2. Quality of Service (QoS): QoS will be configured to prioritize real-time communication traffic, such as VoIP (Voice over IP). VoIP traffic is sensitive to delays and packet loss, so ensuring its timely delivery is critical. QoS will help manage bandwidth allocation, giving priority to VoIP traffic over less critical data.
  3. Wireless Capabilities: The redesign will also include the wiring of all routers and the addition of wireless capabilities. This upgrade will allow both employees and visitors to connect to the network via portable devices, improving flexibility and connectivity.

WAN Backup Design

The current Wide Area Network (WAN) configuration lacks redundancy and is not cost-effective. The proposed solution involves moving from serial leased lines to Dynamic Multiprotocol Label Switching (MPLS). MPLS is a scalable protocol-independent transport mechanism that directs data from one network node to the next based on short path labels rather than long network addresses.

  1. Dynamic MPLS: Dynamic MPLS redundancy is achieved through link aggregation, which allows for the simultaneous use of multiple links. If one link fails, traffic is automatically rerouted through the remaining links, ensuring continuous network availability. This “install and forget” technology reduces the burden on IT staff and improves network reliability.
  2. Cost Efficiency: MPLS is also more cost-effective than traditional leased lines. By aggregating multiple connections, MPLS reduces the need for expensive dedicated lines, providing a scalable solution that can grow with the company.

IP Address Redesign

The IP address redesign will involve route summarization, which reduces the number of routes that must be maintained in routing tables. Route summarization aggregates multiple IP addresses into a single address, simplifying routing and reducing the burden on network resources.

  1. Hierarchical Design: The new IP addressing scheme will follow a hierarchical design, which organizes IP addresses into a structured format that aligns with the network’s physical layout. This structure simplifies network management and supports future growth.
  2. Static IP Configuration: All servers will be configured with static IP addresses to ensure stability and reliability. Static IP addresses do not change, making them ideal for servers that host websites, email services, and other critical applications.

Routing Campus Redesign

The current routing protocol, Enhanced Interior Gateway Routing Protocol (EIGRP), will be retained due to its compatibility with VoIP expansions and its efficiency in using network resources. EIGRP is a distance-vector routing protocol that provides fast convergence and supports equal-cost and unequal-cost load balancing.

  1. Diffusing Update Algorithm (DUAL): EIGRP uses the DUAL algorithm to prevent routing loops, a critical feature for maintaining network stability. Routing loops can cause significant network congestion and downtime, so DUAL’s ability to ensure loop-free paths is a major advantage.
  2. IPv6 Compatibility: As the company grows, transitioning to IPv6 will become necessary. EIGRP’s support for IPv6 makes it a future-proof solution that can adapt to new technologies and address the limitations of IPv4.

American Client WAN Connection Design

The American client connection will be established using a Site-to-Site IPSec VPN. IPSec (Internet Protocol Security) is a suite of protocols that secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet in a communication session.

  1. Cisco ASA Devices: The Cisco Adaptive Security Appliance (ASA) will be used to create the VPN gateway. Cisco ASA devices combine firewall, VPN concentrator, and intrusion prevention capabilities into a single device, providing a comprehensive security solution.
  2. Two-Factor Authentication: To enhance security, two-factor authentication (2FA) will be implemented for remote access. 2FA requires users to provide two forms of identificationā€”such as a password and a security tokenā€”before gaining access to the network, reducing the risk of unauthorized access.

Remote Users

Remote users will also connect to the network via VPN, with two-factor authentication providing an additional layer of security. VPN software will be pre-installed on remote devices, and certificates will be used for authentication.

  1. SSL VPN: For remote users who need to connect to the network via a web browser, Secure Socket Layer (SSL) VPN will be available. SSL VPNs are convenient because they do not require special client software, but they are less secure than IPsec VPNs. A hybrid approach, using both SSL and IPsec, is recommended for different use cases.

Monitoring the Network

Syslog will be implemented for network monitoring. Syslog is a standard for message logging that allows network devices to send event messages to a logging server. These messages can include information about login attempts, port-security alerts, and other critical events.

  1. Troubleshooting: Syslog is invaluable for troubleshooting network issues. By analyzing Syslog messages, IT staff can identify the root cause of problems, such as network congestion or security breaches, and take corrective action.

Conclusion

The proposed network redesign for Widget Corporation will significantly improve the reliability, scalability, and security of its information infrastructure. By implementing redundancy, optimizing IP addressing, and enhancing network monitoring, the company will be better equipped to meet the demands of its growing business. The transition to VoIP, the integration of American clients, and the provision of secure remote access will further support the companyā€™s expansion and modernization efforts.

Netw208 WEEK8 Course Project Final - NETWORK DESIGN PROPOSAL

Introduction

Over the past eight weeks, our team of network administrators has been tasked with researching and prescribing methods to improve the speed and reliability of the Widget Corporationā€™s network infrastructure. Widget Corporation, a leading architectural firm, employs 300 people across 10 global sites, each varying in size and network requirements. The key objectives of this project include seamlessly integrating consumers and partners into the companyā€™s information infrastructure, ensuring network reliability through redundancy, and upgrading the Local Area Network (LAN) infrastructure to support the growing demands of the business.

Our Plan

The proposed plan includes a full campus redesign, WAN backup design, IP addressing scheme rework, VLAN implementation, and network security enhancements. Each of these components is critical to ensuring that Widget Corporationā€™s network infrastructure can meet current demands and accommodate future growth.

Campus Redesign

The redesign of the Widget Corporation campus network will focus on enhancing redundancy and implementing VLANs to segment the network. The existing Cisco 6500 Catalyst Switches will be retained, but Ether-channels will be implemented on their interfaces to combine multiple physical links into a single logical link. This setup not only increases bandwidth but also adds redundancy, ensuring that the network remains operational even if one link fails.

  1. Ether-Channel Implementation: Ether-channel technology combines multiple Ethernet links into one logical link, which provides increased bandwidth and redundancy. This setup ensures that if one link fails, the traffic is automatically rerouted through the remaining links, minimizing downtime and maintaining network performance.
  2. VLAN Configuration: VLANs will be configured to segment the network into different sections based on the departmentā€”such as Design, Human Resources, Sales, and Marketing. This segmentation improves security by isolating sensitive data and reducing the risk of data breaches. Additionally, VLANs help manage network traffic more efficiently, preventing congestion and improving overall performance.
  3. Quality of Service (QoS): QoS will be configured to prioritize VoIP traffic, which is sensitive to delays and packet loss. Ensuring that VoIP traffic is given priority over other types of data traffic will help maintain clear and uninterrupted communication across the network.

WAN Backup Design

The current WAN configuration at Widget Corporation does not support redundancy, making the network vulnerable to outages. To address this, the proposal includes moving from serial leased lines to MPLS or mesh technology, which offers greater reliability and scalability.

  1. MPLS Implementation: MPLS (Multiprotocol Label Switching) is a scalable, protocol-independent transport mechanism that directs data from one network node to the next based on short path labels rather than long network addresses. By implementing MPLS, Widget Corporation can achieve greater redundancy and improve network reliability. MPLS allows for the simultaneous use of multiple links, providing a backup in case of failure and ensuring continuous network availability.
  2. Stand-by ISDN Modem and Site Router: Each site will also be equipped with a stand-by ISDN modem and site router, providing a secondary interface in case of ISP network failure on the local loop. This backup setup will be configured to automatically failover in the event of a local WAN failure, minimizing downtime and maintaining network operations.

IP Addressing Scheme Rework

The existing IP addressing scheme at Widget Corporation is inefficient and does not support the companyā€™s growth. The proposed rework will involve the use of CIDR (Classless Inter-Domain Routing) and hierarchical design to reduce routing overhead and improve network management.

  1. CIDR Implementation: CIDR allows for the efficient allocation of IP addresses by aggregating multiple IP addresses into a single route, which reduces the size of routing tables and improves network efficiency. By implementing CIDR, Widget Corporation can ensure that its network is scalable and capable of supporting future growth.
  2. VLAN Configuration: The network will be divided using VLAN configurations at each level, which will allow for the segregation of corporate data, VoIP, and guest usage. VLANs provide an additional layer of security by isolating different types of network traffic and ensuring that sensitive data is protected.
  3. Guest Network and DMZ Setup: A guest network will be configured using a DMZ (Demilitarized Zone) subnet, which will be outside the protection of the firewall. This setup allows guests to access the internet without compromising the security of the internal network.

American Site Connection

To connect the American site to the Widget Corporation headquarters network, a Site-to-Site VPN (Virtual Private Network) using IPsec (Internet Protocol Security) is recommended. IPsec provides a secure connection between the two sites by encrypting data and ensuring that it cannot be intercepted or tampered with.

  1. VPN Gateway Setup: A VPN gateway, such as a Cisco Adaptive Security Appliance (ASA), will be used to create the secure connection. The Cisco ASA device combines firewall, VPN concentrator, and intrusion prevention capabilities into a single device, providing comprehensive security for the connection.
  2. Encryption and Authentication: The VPN will use Advanced Encryption Standard (AES) with 128-bit encryption or higher to secure the data. Additionally, the VPN will be configured with a pre-shared key (PSK) for authentication, ensuring that only authorized devices can access the network.
  3. SSL VPN for Remote Access: For remote users, SSL VPN will be available, allowing them to connect to the network using a web browser without the need for special client software. While SSL VPN is convenient, it is less secure than IPsec VPN, so a hybrid approach is recommended for different use cases.

Network Monitoring and Security

Monitoring the network is critical for maintaining security and performance. Syslog, a standard for message logging, will be implemented to monitor network devices and log events such as login attempts and port-security alerts.

  1. Syslog Implementation: Syslog provides real-time monitoring of network events, allowing IT staff to quickly identify and respond to issues. Syslog messages can be analyzed to troubleshoot problems, such as network congestion or security breaches, and take corrective action.
  2. Two-Factor Authentication (2FA): Two-factor authentication will be implemented for remote access to enhance security. 2FA requires users to provide two forms of identification, such as a password and a security token, before gaining access to the network. This additional layer of security reduces the risk of unauthorized access and helps protect sensitive data.

Conclusion

The proposed network redesign for Widget Corporation will significantly improve the reliability, scalability, and security of its information infrastructure. By implementing redundancy, optimizing IP addressing, and enhancing network monitoring, the company will be better equipped to meet the demands of its growing business. The transition to VoIP, the integration of American clients, and the provision of secure remote access will further support the companyā€™s expansion and modernization efforts.

NEWT 208 Group Project 1 - WAN Backup Design

Overview

In this project, we are tasked with redesigning the WAN (Wide Area Network) for a campus to address the issues currently faced by the architects, engineers, and users. The key focus of the redesign is on improving network reliability by introducing redundancy, optimizing existing equipment, and proposing a new WAN backup design. The ultimate goal is to ensure continuous network availability, even in the event of equipment failure.

Campus Redesign

The current campus network lacks redundancy, which means that if any critical piece of equipment fails, the entire network could go down, resulting in significant downtime and productivity loss. The proposed solution involves adding a second 6500 switch on top of the three already implemented at each site connected to the ISP. This additional switch will act as a backup, taking over in case the primary switch fails.

  1. Redundancy Implementation: Redundancy is a critical feature in any network design. By adding an additional 6500 switch at each site, the network gains an extra layer of reliability. In the event of a switch failure, traffic can be seamlessly redirected to the backup switch, ensuring that network services remain uninterrupted.
  2. Switch Replacement: The existing Ethernet hubs, which are a source of network slowness, will be replaced with smaller 3560-CX switches. Unlike hubs, which broadcast incoming traffic to all ports, switches direct traffic only to the intended destination, significantly reducing unnecessary network traffic and improving overall bandwidth efficiency.
  3. Packet Switching Implementation: The proposal includes the implementation of packet switching, a method that divides data into packets before they are transmitted. Packet switching is more cost-effective than leased lines because it allows the carrier to use virtual circuits between customers, optimizing the use of available bandwidth.

WAN Backup Design

A robust WAN backup design is essential for maintaining network reliability, especially in the face of potential equipment failures or outages. The proposed design includes several key components to improve the current WAN setup.

  1. Trunking the Second Switch: To increase bandwidth and allow for future growth, the second switch will be trunked to the first one with the ISP WAN link. Trunking involves combining multiple network connections to increase the overall bandwidth available, allowing for more simultaneous connections and reducing the likelihood of network congestion.
  2. Access Control Lists (ACLs): To further optimize network traffic, ACLs will be created and applied to specific VLANs for each department in the company. ACLs are a set of rules that control the incoming and outgoing network traffic, ensuring that only authorized traffic is allowed to pass through the network interfaces. This helps in reducing unnecessary traffic and improves overall network performance.
  3. Dynamic MPLS Redundancy: The proposed WAN backup design includes the implementation of Dynamic MPLS (Multiprotocol Label Switching). MPLS directs data from one network node to another based on short path labels rather than long network addresses, which speeds up the data transfer process. Dynamic MPLS also supports redundancy by aggregating multiple connections, ensuring that traffic is automatically rerouted if one connection fails.

Benefits of the Proposed Design

The proposed WAN backup design offers several key benefits that address the current network’s shortcomings and future needs.

  1. Improved Reliability: By introducing redundancy through the additional 6500 switch and trunking, the network becomes more reliable. The backup switch ensures that even if the primary switch fails, network services remain operational, minimizing downtime and its associated costs.
  2. Increased Bandwidth and Scalability: Trunking the second switch with the ISP WAN link not only increases the available bandwidth but also allows for future network expansion. As the company grows, the network can easily accommodate additional connections without compromising performance.
  3. Enhanced Security and Traffic Management: The use of ACLs and VLANs helps in managing network traffic more effectively, ensuring that only authorized traffic is allowed to pass through the network. This reduces the risk of security breaches and improves overall network performance.

Conclusion

The proposed WAN backup design for the campus addresses the current issues of redundancy, bandwidth, and traffic management. By implementing additional switches, trunking, ACLs, and Dynamic MPLS, the network will become more reliable, scalable, and secure. These improvements will not only meet the current needs of the company but also ensure that the network can support future growth and technological advancements.

NEWT 208 WEEK 1 QUIZ

Overview

This quiz covers fundamental concepts in network design, focusing on the hierarchical design of LANs (Local Area Networks), the OSI model, and WAN technologies. The quiz includes questions on the layers of the OSI model, the hierarchical LAN campus design, and specific WAN technologies like frame-relay and point-to-point protocols.

Question 1: Hierarchical LAN Campus Network Design

A typical enterprise hierarchical LAN campus network design usually includes a three-layer design. The first of these three layers is the Access Layer.

  • Explanation: The Access Layer is responsible for connecting end devices, such as computers and printers, to the network. It provides access to the rest of the network and is the first point of entry for users. The Access Layer plays a critical role in managing network traffic, implementing security policies, and ensuring that devices can connect to the network.

Question 2: Network Model in Design

A network model is a useful high-level tool for designing a reliable network infrastructure. It breaks the complex problem of network design into smaller and more manageable areas. This is known as creating network layers.

  • Explanation: Network models use layers to separate different functions of the network, making it easier to manage and troubleshoot. The most common model is the OSI model, which has seven layers, each responsible for different aspects of network communication.

Question 3: Distribution and Core Layer Functions

The three-tier hierarchical design maximizes performance, network availability, and the ability to scale the network design. When the Distribution layer and Core layer functions are implemented by a single device, this is known as a collapsed core.

  • Explanation: A collapsed core design is used in smaller networks where combining the Distribution and Core layers into a single layer simplifies the network architecture without compromising performance. This design reduces costs and simplifies management but may not be suitable for large-scale networks.

Question 4: OSI Layers in WAN Networks

WAN networks primarily work on the Physical, Data Link, and Network layers of the OSI Reference model.

NETW208 Week 7 iLab Report - TROUBLESHOOTING WAN vLAB

Overview

The primary objective of this lab was to develop the skills necessary to troubleshoot WAN (Wide Area Network) connectivity issues, identify and fix configuration errors, and restore full network connectivity. WANs are critical for connecting remote sites and enabling communication across large geographical areas, making it essential for network administrators to understand how to diagnose and resolve issues that may arise in such networks. This report outlines the steps taken during the lab, the commands used, and the key lessons learned.

Task 1: Show IP Route Command

The first task involved executing the show ip route command on the NewYork router. This command displays the router’s routing table, which contains the routes that the router uses to forward packets. The routing table should include all networks that the router can reach.

  • Missing Networks: After executing the command, it was observed that the networks 192.168.2.0/24 and 192.168.4.0/24 were missing from NewYork’s routing table. This indicates that the router does not have routes to these networks, which could lead to communication issues with devices on those networks.

Task 2: Show Controllers and Interface Commands

In Task 2, the show controllers s1/0 command was executed on the Tokyo router. This command displays information about the router’s serial interfaces, including whether the interface is a Data Communications Equipment (DCE) or Data Terminal Equipment (DTE).

  • Clock Rate Configuration: The output revealed that the s1/0 interface of the Tokyo router is a DCE, which means it is responsible for providing the clock rate for the connection. However, the clock rate was not configured, leading to link flaps. After setting the clock rate using the appropriate command, the interface status changed to “up and up,” indicating that the connection was stable.
  • Interface Parameters: For a serial connection to be operational, it is essential to configure the correct IP address, subnet mask, and clock rate (on the DCE end). These parameters ensure that the interface can communicate effectively with other devices on the network.

Task 4: Ping Command and Static Routing

In Task 4, the ping command was used to verify connectivity between different segments of the network. The successful execution of the ping command indicates that the devices can communicate with each other across the WAN.

  • Routing Method: The lab also involved analyzing the routing method used to populate the route tables. The output indicated that static routing was employed, as denoted by the “S” in the routing table entries. Static routing is a simple and effective method for small networks but may not scale well in larger, more dynamic environments.

Troubleshooting Issues on the Tokyo Router

Several issues were identified and resolved on the Tokyo router during the lab. The primary problems included the absence of a clock rate on the DCE interface and the incorrect default route configuration. These issues were addressed by applying the correct clock rate command and fixing the routing configuration.

Summary

This lab provided valuable hands-on experience in troubleshooting WAN connectivity issues. By using commands such as show ip route, show controllers, and ping, we were able to identify and resolve problems with network configurations. The lab emphasized the importance of understanding WAN protocols, interface configurations, and routing methods. These skills are critical for maintaining the reliability and performance of production networks.

Conclusion

The troubleshooting techniques and tools learned in this lab are essential for network administrators responsible for maintaining WANs. Understanding how to diagnose and resolve connectivity issues ensures that networks remain operational and can support the communication needs of an organization. This experience will be beneficial in both academic studies and professional careers in network administration.

These tools are critical for monitoring and managing network performance, ensuring that any issues can be quickly identified and addressed. The quiz tests knowledge on the configuration and operation of these tools, as well as the commands used to manage them on routers and other network devices.

Question 1: Syslog Port

Syslog uses UDP port 514 to send event notification messages across IP networks.

  • Explanation: Syslog is a protocol used to send system log or event messages to a specific server, known as a Syslog server. It is widely used for monitoring and troubleshooting network devices. Syslog operates over UDP port 514, allowing for the efficient transmission of log messages without the overhead of establishing a TCP connection.

Question 2: Syslog Severity Levels

A Syslog Warning message has a severity level of 4.

  • Explanation: Syslog messages are categorized into different severity levels, ranging from 0 (Emergency) to 7 (Debug). A severity level of 4 corresponds to a Warning message, indicating a potential issue that should be investigated but does not immediately affect network operations.

Question 3: Configuring Syslog Messages

To control the type of messages that will be sent to a Syslog server, the command to use when configuring Syslog for the type of messages to log is None of the Above.

  • Explanation: The correct command to control the type of Syslog messages sent to a server is logging trap level, where “level” specifies the severity level of messages to be logged. This command allows administrators to filter messages based on their importance, ensuring that only relevant logs are recorded.

Question 4: SNMP Manager Requests

There are two primary SNMP manager requests: get and set.

  • Explanation: SNMP (Simple Network Management Protocol) is used for collecting and organizing information about managed devices on IP networks. The get request retrieves information from a network device, while the set request is used to modify the configuration of a device.

Question 5: SNMP Information Base

The part of SNMP that is referred to as a Virtual Device Store and organizes variables associated with devices and buffers in a hierarchical order is called the Management Information Base (MIB).

  • Explanation: The MIB is a database used by SNMP to manage the entities in a computer network. It organizes variables that are accessible via SNMP in a hierarchical structure, allowing for efficient monitoring and control of network devices.

Question 6: Optional SNMP Command

The optional command that can be entered on a router when configuring SNMP to document the area where the device is located is snmp-server location text.

  • Explanation: The snmp-server location command is used to specify the physical location of a device. This information is useful for network administrators when managing large networks with devices spread across multiple locations.

Question 7: NetFlow Development

Historically, NetFlow was developed because networking professionals needed a simple and efficient method for tracking TCP/IP traffic.

  • Explanation: NetFlow is a network protocol developed by Cisco for collecting IP traffic information. It provides detailed traffic analysis, allowing administrators to monitor the flow of data across the network, identify usage patterns, and troubleshoot network performance issues.

Question 8: NetFlow Capture Command

The command used to capture outgoing NetFlow data for monitoring on an interface is ip flow egress.

  • Explanation: NetFlow can monitor both ingress (incoming) and egress (outgoing) traffic on an interface. The ip flow egress command is used to enable the capture of outgoing traffic data, which is then sent to a NetFlow collector for analysis.

Question 9: NetFlow Summary Command

The command that can be used on a router to display a summary of NetFlow accounting statistics and which protocols used the highest volume of traffic is show ip cache flow.

  • Explanation: The show ip cache flow command provides a summary of NetFlow data, including information about the most active traffic flows and the protocols generating the most traffic. This command is useful for identifying network congestion points and optimizing traffic management.

Question 10: NetFlow Export Version

When enabling NetFlow, the command to use on a router that indicates the version to follow when formatting the NetFlow records is ip flow-export version #.

  • Explanation: NetFlow records can be exported in different formats, depending on the version specified. The ip flow-export version command allows administrators to define the version of the NetFlow export format, ensuring compatibility with the NetFlow collector being used.

Conclusion

This quiz covers fundamental aspects of network monitoring and management, focusing on Syslog, SNMP, and NetFlow. Mastering these tools is essential for maintaining network performance, identifying potential issues, and ensuring the security and reliability of the network infrastructure.
