rip v1 is classful, it will only advertise networks that have same subnet
mask as the interface it is being advertised out, same for receiving routes.
You can either change to rip v2, or put a secondary address on the serial
interfaces that have /24 mask with in the same class b network.

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?
