Thanks for the input, I did find my error though. After
debuging I found that as I only had link-local addresses
configured across the frame link i.e no site local-address,
the source address used for communications was set to the
ethernet (this interface had a site-local add configured).
Problem was that the ethernet was not part of the RIP
network.
2 ways to fix this
1. Add site-local addresses to the frame link.
or
2. Add the ethernet as part of the RIP network.
