If I understand your topology, the problem is that you are running RIP and
IGRP with a discontiguous classfull network. Let me rephrase that. <g>
It appears that your network looks like this:
A 10.1.0.0 --------- 192.168.10.0 ---------- B 10.2.0.0
RIP and IGRP cannot pass subnet mask information in their routing updates.
This means that router A above thinks that the entire 10.0.0.0 network --not
just 10.1.0.0/16-- resides to its left. Router B think the entire
10.0.0.0/16 network resides to its right. These routers will get very
confused and will behave in the manner that you're seeing.
To correct this behavior you must run a classless routing protocol that
includes subnet mask information in its updates, so your options are eigrp,
ospf, and is-is. This will solve your problem.
I hope that makes sense. I just woke up and I'm still pretty groggy!
