Scenario 5-1: Configuring EIGRP
In this scenario, you configure eight Cisco routers for IP routing using a Class B (/16) network 220.127.116.11 with a Class C subnet mask (255.255.255.0 or /24). The serial links will use a two-host subnet to demonstrate the use of VLSM with EIGRP.
Assume the core backbone network resides on the Ethernet between R1 and R2.
Figure 5-2 displays a network with seven routers in AS1 and one remote router in AS2.

The IP address assignment for the WAN links is described in Table 5-3. Note the use of VLSM across the WAN Links.
