ROUTER INTERFACE CONFIGURATION

LAB 9-2: ROUTER INTERFACE CONFIGURATION

Objective: Configure IP address assignments to router interfaces

Objective: Document all IP address that are reachable via the ICMP Ping command

after interface configurations are complete.

From the Router console

Step 1 - Enter user exec mode with the cisco password

Step 2 - Enter ping xxx.xxx.xxx.xxx for all IP interfaces in lab configuration

and Document in your LAB Engineering Journal the responses from

typing the ICMP Ping command

Question ? Did any of the router interfaces respond with a successful

ping.

Answer - __________ ______ ____ ________

Step 3 - Enter enable exec mode with the class password

Step 4 - display the current running-configuration

Question ? What is the router command to accomplish this.

Step 7 - Enter ip address xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy

Were xxx.xxx.xxx.xxx equals the ip address you want to assign to the interface

and yyy.yyy.yyy.yyy equals the subnet mask you want to assign to the interface.

Base these assignments on the information in the LAB diagram

Step 8 - Enter exit

This will take you back one level in the enable exec.

Question ? What changed in the router prompt.

you must complete step 11. If the change is not written to memory

it will go away next time the router reboots.

Step 11 - Enter the ping xxx.xxx.xxx.xxx command (were xxx.xxx.xxx.xxx is the ip

address of the interface you just configured ) to verify that the interface is

up and alive.

Step 12 - Enter the copy running start command at the router prompt.

This command will permanently write the configuration change to memory

Step 13 - Repeat steps 5 - 12 for all interfaces on you router.

Question ? What commands will tell you how many and what kind

of interfaces are on your router.

Answer - __________ ______ ____ ___________

Step 14 - Enter the reload command at the router prompt.

Verify that the interface addresses in the running configuration are the

same as what is shown in the LAB diagram.
