Use the

command to provide a description for this interface.
Step 12.
R1(config-if)#
description R1 LAN
R1(config-if)#
Configure the Serial 0/0/0 interface with the IP address 192.168.2.1/24.
Step 13.
Set the clock rate to 64,000.
Note:
Because the routers in the labs will not be connected to a live leased line, one of the routers will need to
provide the clocking for the circuit. This is normally provided to each of the routers by the service provider. To
provide this clocking signal in the lab, one of the routers will need to act as the DCE on the connection. This
function is achieved by applying the
clock rate 64,000
command on the Serial 0/0/0 interface, where the DCE
end of the null modem cable has been connected. The purpose of the
clock rate
command is discussed further in
Chapter 2, “Static Routing.”

Task 7: Perform Basic Configuration of Router R2
For R2, repeat Steps 1 through 10 from Task 6.
Step 1.
Configure the Serial 0/0/0 interface with the IP address 192.168.2.2/24.
Step 2.
R2(config)#
interface serial 0/0/0
R2(config-if)#
ip address 192.168.2.2 255.255.255.0
R2(config-if)#
