Hello Guys,
I need help . am working on some lab scenarios.
i have 3 routers connected R4,R5 and BB
R4 is connected to the BB router through the network 204.12.1.0 and the BB
router is advertising routes 30.0.0.0 and 31.0.0.0 network via rip as shown
in
the below output
R4#sh ip route rip

R4 as a dual connection to R5 via serial and a frame relay link and are both
runing RIP.
The problem is that R4 is continually poisoning the 30.0.0.0 and 31.0.0.0
learned from BB router. and it has a next hop of 0.0.0.0 as shown from the
debug ip rip on R4

This makes pings from R5 to the 30.0.0.0 and 31.0.0.0 net time out
occasionally .
Can somebody explain why this is happening?
