Initial Configuration

Adapting the topology shown in Figure 2-50 to your own router interface, assign an IP address to the serial interface on router R1 and configure the interface for PPP encapsulation. Set the bandwidth of the interface connecting to R2 to 128 kbps, using the bandwidth 128 command. Administratively bring up the interface.

Assign IP addresses to the two serial interfaces on router R2 and configure the interfaces for PPP encapsulation. Set the bandwidth of the interface connecting to router R1 to 128 kbps, using the bandwidth 128 command. Set the clock rate on the interface connecting to router R1 to 128 kbps with the clock rate 128000 command. Set the bandwidth of the interface connecting to router R3 to 2 Mbps, using the bandwidth 2000 command. Administratively bring up the interfaces.

Assign an IP address to the serial interface router R3, and configure the interface for PPP encapsulation. Set the clock rate on the serial interface to 2 Mbps with the clock rate 2000000 command and indicate the interface bandwidth as 2 Mbps with the bandwidth 2000 command. Administratively bring up the interface.

Configure a routing protocol of your choice on the routers such that all routers can see the networks associated with each of the serial interfaces in the topology.

Issue the show ip route command on R1, R2, and R3 to verify that the following networks are visible to each router:

• 10.1.1.0/24

• 10.7.7.0/24

From a console connection to the R1 router, ping the 10.7.7.2 interface (that is, R3's serial interface) to verify Layer 3 connectivity across the pod.
