I can’t seem to get RIP or OSPF to correctly propagate over PPTP links.
I have MT routers both ends and with RIP I setup neighbour iP addresses for each end of the PPTP link, but for some reason routes on the Client end get propagated to the PPTP server end, but the Server end routes do not appear on the Client end.
I have “Redistribute Connected Routes” enabled on both ends and “Redistribute OSPF Routes” enabled on the Server end.
OSPF quite happily distributes the routes on the main network, but no matter what I do it won’t propagate over PPTP. The only examples I can find are for Ethernet connected networks, is there an example of how to do the same over PPTP? I would have thought it should be the same for PPTP as this should be a transparent tunnel.

Here’s a bit more info:-
All routers running v2.9.43
Main site router is running on x86 hardware.
Two remote sites, one on x86 and one is an RB532. The RB532 has fully populated route lists from server, but x86 based system only has local routes, nothing from server. Both routers are configured exactly the same for PPTP and RIP. Is this a bug in the x86 code version?
Don’t worry, I’ve fixed it myself. It seems that after configuring RIP or OSPF you have to reboot the router in order for it to work properly. Seems a bit weird as nothing else, other than a package upgrade, needs a reboot.
I’ve had many issues with OSPF running over a PPTP connection.
We run two PPTP connections over two different Internet lines: A DSL and Cable Internet connection. We recently replaced one of the routers, but it seems that OSPF would not properly work on the other side (the router that was not replaced) until we restarted it. It was using another secondary location to route traffic through it (so it indirectly took 3 hops instead of the more directly available 2 hops via either one of the direct PPTP connections which would connected just fine).
So after restarting it worked just fine. A few days later the primary PPTP (the DSL) connection went down for a few moments, the OSPF switched over to the Cable for the primary route, but then WOULD NOT go back to the DSL no matter what I did. I made sure that the interface priorities were set very high for the other interfaces, but it would rather jump through an indirectly secondary location and take 3 hops instead of using the DSL (which had a actively running PPTP connection). It only started working after I disable and re-enabled the PPTP connection for the DSL.
I have heard from others that routing protocols have issues running over PPTP connections, are these problems still prevalent?
