Hello Rob
I receive the routes from RIP and his route is OK.
44.17.0.128/31 via 67.49.91.65 dev tunl0 proto ampr-ripd onlink
It's coming through today after I informed the sysop his block was being omitted. I think he re-entered his block in the portal, but i'm not positive. I know on two systems I help out on his block was not coming through via rip.
