Split horizon IS enabled by default: Serial0.1 is up, line protocol is up Internet address is x.x.x.x Broadcast address is 255.255.255.255 Address determined by non-volatile memory MTU is 1500 bytes Helper address is not set Directed broadcast forwarding is disabled Outgoing access list is not set Inbound access list is not set Proxy ARP is enabled Security level is default Split horizon is enabled ICMP redirects are always sent ICMP unreachables are always sent ICMP mask replies are never sent IP fast switching is enabled IP fast switching on the same interface is enabled IP Feature Fast switching turbo vector IP multicast fast switching is disabled IP multicast distributed fast switching is disabled IP route-cache flags are Fast Router Discovery is disabled IP output packet accounting is disabled IP access violation accounting is disabled TCP/IP header compression is disabled RTP/IP header compression is disabled Probe proxy name replies are disabled Policy routing is disabled Network address translation is enabled, interface in domain outside WCCP Redirect outbound is disabled WCCP Redirect exclude is disabled BGP Policy Mapping is disabled And this would be configuration snip: interface Serial0 no ip address encapsulation frame-relay IETF no fair-queue frame-relay lmi-type q933a ! interface Serial0.1 point-to-point ip address x.x.x.x 255.255.255.252 ip nat outside no cdp enable frame-relay class circlass frame-relay interface-dlci 209 IETF IOS is 12.1(3) and platform is 1720.
