Topology Diagram

Learning Objectives
Upon completion of this lab, you will be able to:
• Cable a network according to the Topology Diagram.
• Erase the startup configuration and reload a router to the default state. • Perform basic configuration tasks on a router.
• Configure and activate Serial and Ethernet interfaces. • Test connectivity.
• Gather information to discover causes for lack of connectivity between devices. • Configure a static route using an intermediate address. • Configure a static route using an exit interface.

• Compare a static route with intermediate address to a static route with exit interface. • Document the network implementation.

In this lab activity, you will create a network that is similar to the one shown in the Topology Diagram. Begin by cabling the network as shown in the Topology Diagram. You will then perform the initial router configurations required for connectivity. Use the IP addresses that are provided in the Addressing Table to apply an addressing scheme to the network devices. After completing the basic configuration, test connectivity between the devices on the network. First test the connections between directly connected devices, and then test connectivity between devices that are not directly connected. Static routes must be configured on the routers for end-to-end communication to take place between the network hosts. You will configure the static routes that are needed to allow communication between the hosts. View the routing table after each static route is added to observe how the routing table has changed.

Task 1: Cable, Erase, and Reload the Routers.

Step 1: Cable a network that is similar to the one in the Topology Diagram.

Step 2: Clear the configuration on each router.
Clear the configuration on each of the routers using the erase startup-config command and then reload the routers. Answer no if asked to save changes.

Task 2: Perform Basic Router Configuration.

Step 1: Use global configuration commands.
On the routers, enter global configuration mode and configure the basic global configuration commands including: • hostname
• no ip domain-lookup
• enable secret

Step 2: Configure the console and virtual terminal line passwords on each of the routers. • password
• login

Step 3: Add the logging synchronous command to the console and virtual terminal lines. This command is very helpful in both lab and production environments and uses the following syntax:

Router(config-line)#logging synchronous

To synchronize unsolicited messages and debug output with solicited Cisco IOS software output and prompts for a specific console port line, auxiliary port line, or virtual terminal line, we can use the logging synchronous line configuration command. In other words, the logging synchronous command prevents IOS messages delivered to the console or Telnet lines from interrupting your keyboard input.

R1 is shown here as an example. Add logging synchronous to the console and virtual terminal lines on all routers.

R1(config)#line console 0
R1(config-line)#logging synchronous
R1(config-line)#line vty 0 4
R1(config-line)#logging synchronous

Step 4: Add the exec-timeout command to the console and virtual terminal lines. To set the interval that the EXEC command interpreter waits until user input is detected, we can use the exec-timeout line configuration command. If no input is detected during the interval, the EXEC facility resumes the current connection. If no connections exist, the EXEC facility returns the terminal to the idle state and disconnects the incoming session. This command allows you to control the amount of time a console or virtual terminal line can be idle before the...
