Scenario 2-3: Basic IGRP
This scenario is designed to introduce you to the basics of IGRP and EIGRP configurations.
Once more, revisit the two-router scenario. IGRP is a classful routing protocol, so you have to change the IP addressing back to a non-VLSM network. In this scenario, you use a different class address as well. Figure 2-4 displays the network topology and IP addressing scheme.
Figure 2-4. Basic IGRP/EIGRP Network
This scenario starts with IGRP and then changes the routing protocol to EIGRP.
In this basic scenario, you configure the two routers R1 and R2 for IGRP using the same administrative domain. To share information between routers ...
