Split-horizon is enabled by default on all links when SAF is configured. When using remote static neighbors across a non-SAF network in a hub-and-spoke topology, generally all remote neighbors will be configured with a single Loopback interface as their source. This results in the Loopback interface behaving as a multipoint link on the hub router.<br /> <br /> Disable split-horizon on multipoint links on the hub router when SAF advertisements need to be advertised between spoke routers. <br /> <br /> ==Related show Commands==<br /> <br /> sh eigrp service-family ipv4 int detail<br /> <br /> <br /> Example:<br /> [[Image:Show_eigrp_service_ipv4_int_detail.jpg‎]]<br /> <br /> ==Related Information==<br /> [http://www.cisco.com/web/psa/products/index.html Technical Support &amp; Documentation - Cisco Systems]<br /> [http://www.cisco.com/go/saf SAF Product Page - Cisco Systems]<br /> [http://www.cisco.com/en/US/docs/ios/saf/configuration/guide/saf_cg.html Cisco IOS SAF Configuration Guide - Cisco Systems]<br /> <br /> [[Category: IOS Software and NX-OS Software Configuration Examples]]<br /> [[Category: Router Configuration Examples]]</div>
