Also, as soon as I configure ip rip triggered on the point-to-point subinterface I create between R2 and R4 (as per IPExpert's topology), I totally loose routes. I have removed "ip rip triggered" in the config below:
R4(config-subif)#do sh run int s0/0.1 Building configuration... Current configuration : 179 bytes ! interface Serial0/0.1 point-to-point ip address 150.100.24.4 255.255.255.0 ip rip authentication key-chain R2R4 snmp trap link-status frame-relay interface-dlci 402 end R2#sh run int s0/1.24 Building configuration... Current configuration : 180 bytes ! interface Serial0/1.24 point-to-point ip address 150.100.24.2 255.255.255.0 ip rip authentication key-chain R2R4 snmp trap link-status frame-relay interface-dlci 204 When I run debug I see R2 recieving routes from R4 but not sending anything back to R4. Can anyone see why? Thanks. Regards, Samir Idris.
