This is because RIPv1 does not support VLSM. Try using RIP Version 2
with "no auto-summary" feature. I think it can solve the problem :)

Hi Jason,
The debug result of your configuration is absolutely right. Nothing
wrong.
Please try to read Jeff Doyle Volume I and the exercise after that. And
then
read all the topics about Rip in CCO, you will get the answer easily.
The Mask
mismatch in Version I of Rip would lead to this result.
Richard Hanks.

Thought this would be simple but apparently not! Just trying to set
up
RIP b/w two routers and it just won't happen. How am I making this
difficult?
