EIGRP over Frame Relay: Static Mappings

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

NOTE: To deploy EIGRP over a physical interface using static mappings and thus disabling Inverse ARP no changes are needed to the basic EIGRP configuration. Only manual IP to DLCI mapping statements are required on all three routers.

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.
