I have a lab scenario with 4 routers connected in a chain (RTRa->RTRb->RTRc->RTRd). RIP v1 is configured on all routers. When I configure a default route i.e 'ip route 0.0.0.0 0.0.0.0 null 0' on RTRb or RTRc the default route appears in all my routing tables automatically. If however, I place the default route on either RTRa or RTRd the route is not propagated throughout the rip domain. I have to force the issue with 'redistribute static' and all is well. Can anyone explain what is happening here ?
In earlier versions of RIP, the default route created using the ip route 0.0.0.0 0.0.0.0 was automatically advertised by RIP routers. In Cisco IOS Software Release 12.0T and later, RIP does not advertise the default route if the route is not learned via RIP. It may be necessary to redistribute the route into RIP.
