6.6 Configuring EIGRP
6.6.4 EIGRP for IPX SAP configuration example
Figure   provides an example of a SAP incremental configuration.

The definitions in Figure explain the setups used.

The router FDDI interface (F0) carries IPX backbone traffic between the two IPX RIP networks. The ipx sap-incremental eigrp 1 command configures incremental-only SAP updates on the FDDI interface for EIGRP AS 1. As a result, the router sends only SAP changes from another EIGRP router on interfaces F0 and S0.
