Interface Connectivity and IP Addressing

   

The approach used in this chapter to configuring each of the router interfaces is based on types of interfaces. For example, you will configure all the Frame Relay interfaces first. You will enter all the necessary commands to bring up the Frame Relay connection and assign an IP address to the interface, and then you will verify connectivity to all directly connected interfaces by using the ping command.

After the Frame Relay interfaces are configured, you will configure all of the point-to-point serial interfaces and assign them IP addresses; then you'll move on to Ethernet and then Token Ring. This will give you the opportunity to focus on each of the data link layer technologies and how to configure them. This is an important section of the lab because you cannot configure the different routing protocols until you have all interfaces configured with IP addresses and have complete IP connectivity to directly connected interfaces. ( Directly connected interfaces refers to router interfaces connected to the same physical segment.)

The lab objectives to complete in this chapter are as follows :

  • Configure all routers to have a description on all active interfaces (except loopback interfaces) stating the router and interface to which they are connected.

  • Create loopback interfaces on all routers. Use IP address 192.169. X. X /24 (where X is the router number). So, R1 would have a loopback address of 192.169.1.1/24, R2 would be 192.169.2.2/24, and so on.

IP Addressing

Refer to the lab diagram in Figure 7-1 for IP addressing assignments. Don't forget to look at the network mask. The BRI ports on R5 and R6 should use the IP addresses 192.168.200.1/30 and 192.168.200.2/30, respectively.

As mentioned earlier, you begin configuring the lab with the routers that have interfaces connected to the Frame Relay network. Before you start configuring the routers, however, you should briefly review Frame Relay and its components .
