Lab 7 Configuring Static Routes Name:

Overview

The overall objective of this lab is to configure static routes on two routers so that there is a network connection between the computers in the two LANs. You will have to configure the computers IP address, the gateway address, and the IP addresses for the appropriate router interfaces. This will require that the serial connection between routers be configured and enabled. In addition, you will also configure static routing between the two networks.

How to set the clock rate for the router.

Which router controls the clock rate, DCE, DTE?

How to you configure the IP address, subnet mask, and default gateway for the computers in your LAN.

How is the gateway address for your LAN router configured?

The steps for configuring the hostname for your router

The steps for configuring the router interfaces IP addresses and subnet masks.

The commands for configuring a static route from your LAN router to the adjacent LAN router.

List two commands that can be used to verify that the routes are configured on the router.

Use the computers in your LAN to ping the computers in the adjacent LAN.

Use the proper command in the router to trace the route from your router to a host in the other LAN.

Use the command to make a telnet connection to your router. How do you enable a telnet connection to the router?

Use the router command that displays the network routes stored in your routers routing table.

Use the command to save your router configuration to NVRAM.

What command is used to verify the routing protocol being used? What are two commands that can be used to display the routing protocol?

Reference Tables

For convenience, Table 1 provides the IP addresses and mask necessary for all interfaces used to complete this lab.

Table 1 Computer IP Addresses, subnet masks and gateway address for this lab.

Detailed Lab Steps

Task#1

Configure a static route to the adjacent LAN, LAN-A to LAN-B. Use the IP addresses provided in Table 1. You will be asked to verify that the computers in your LAN can ping the neighbor LAN. Note that a serial interface is being used to interconnect the LANs. You are configuring routing for both a 192.168.20.0 and 172.16.75.0 networks. A subnet mask of 255.255.255.0 is being used.

Configure the hostname for your routers (R1 should be renamed the CLIDLANA and R2 should be renamed CLIDLAN-B). Provide screenshots of the router prompt and command used to configure the routers hostname.

Configure the gateway address for your LAN routers (Fa0/1) according the addresses provided in Table 1. You will also need to enable the interfaces. Screenshot the commands used to configure the IP addresses, the subnet mask for your gateway and the command used to enable the interface.

Configure the additional (Fa0/0) router interfaces IP addresses and subnet masks according the addresses specified in Table 1. Use the proper command to verify that the interfaces are properly configured. Screenshot the prompts and the commands used to accomplish this task.

Configure static routes from the LAN-A router to the LAN-B router and from LAN-B router to back to the LAN-A router. Use two commands to verify that the routes are configured. Screenshot the commands used.

What does it mean that the Gateway of last resort is not set?

Use the computers in each LAN to ping the computers in the adjacent LAN. Screenshot the commands used.

Use the proper command to trace the route from a PC in LAN-A to a host in the LAN-B. Your trace should pass through two routers. Screenshot the command used and record the trace information. How may hops did you record? *trace (ip address) P 6

Use the router command that lists the network routes stored in the LAN-A routers routing table. Screenshot the routes. Are all of the routes defined for your network?

Use the command to save your router configuration to the startup configuration. What command did you use? Use the proper command to verify the configuration has been saved to NVRAM. What command did you use?

What command is used to verify the routing protocol being used? List two router commands.

Task #2 Configuration List

In this task you are to issue the show running-configuration command from the LANA# prompt. The following is a partial list of the items displayed when you issue the command show running-configuration [sh run]. Your task is to define each item and its purpose. You may need to go to the Cisco website (www.cisco.com) and look up what each of these commands mean.
