Hi,
I'm not sure if this a bug or what, but I have trouble to distribute
loopback interfaces from a 2612 with IOS 12.1.13 to 2503 with IOS 12.1.13,
but have no problems from 2503 to 2612.
The topology is
EIGRP--R2<---RIP--->R1(2503)<--RIP-->R7(2612)
Everything is in 150.150.x.x subnet, R7 has two loopback interfaces, but rip
could not send them to R1. When I add another loopback interface on R1, R7
sees it without any problems.
There's no filters in R7 or R1 and I've reloaded both R7 and R1, but got the
same result. I will try 12.1.11 and see if I still get the same problem.
Thanks,
Chang
