Task 12.6 solution guide has you change the IP on R2, adding a secondary
address
to perform this task. I find that this is breaking RIP between R1 and R2, even
after putting the no validate-update-source command in. What I'm finding is
that
R2 is able to peer with R1 via RIP, but R1 isn't peering with R2 via RIP. Doing
a debug, what I see is that R2 sends the packet with a source of the primary IP
on the interface of 150.100.68.2, but R1 doesn't know how to deliver the packet
back as it's not getting RIP from R2. If I put a static route on R1 to
150.100.68.2 towards R2, this fixes the issue.
Can someone troubleshoot what the issue is here?
