I have 2 routers point-to-point subinterfaces Frame Relay. On both EIGRP is running. I faced the following problem recently.
The hub router did not received any routes from the spoke router. We figured out that the WAN link probaply did not let multiaccess traffic to pass through it since all other traffic was passing ok but the routes (since EIGRP uses multiaccess traffic(18.104.22.168)for updates)were not learned from the hub router. We configured tunneling on both routers and now it's ok.
Is it possible the Telco company for a reason to forbit multiaccess traffic between two nodes?
Is there another problem that we did not think about it?
Thanks a lot
