I have just tried connecting an RB153 board running 2.9.39 to an existing network running RIP v2.
It gets the updates, but the routes time out after 3 minutes, and are dropped from the table. If i remove the RIP network address, and then add it again it recieves the routes again, but then times out after 3 minutes.
Other devices (non mikrotik) are continuing to recieve routes fine.
Any ideas on why this might be happening would be great.
A few other networks mates have played with it for a bit, and think its possibly a bug with MT.
