EIGRP over Frame Relay: Dynamic Mappings

Figure 2-1 shows the network topology for the configuration that follows, which shows how to configure EIGRP over Frame Relay using dynamic mappings.

NOTE: To deploy EIGRP over a physical interface using dynamic mappings relying on Inverse ARP no changes are needed to the basic EIGRP configuration.

NOTE: In EIGRP, split horizon is disabled by default on the physical interface. Therefore, R2 and R3 can provide connectivity between their connected networks. Inverse ARP does not provide dynamic mappings for communication between R2 and R3; this must be configured manually.
