I have this topology I have OSPF configured and when all of my links are working i dont have connecction problems between 10.20.26.1 and 10.20.34.1, the primary road is a L2 rin with REP between IE3000 switches and the secondary is the connections between routers. If i  disconnect the L2 ring connection OSPF change the road to the routers connections. thats ok. But i am experimenting something strange, if i only cut the link between ie3000 and 4500 the ie3000 with the 10.20.34.2 network lose all of the networks learned with OSPF until i cut also the connection from this ie3000 to the ring, I've made a debug ip routing and when everything is connected the router ie3000 (10.20.34.2) knows the network 10.20.26.1, but if i cut the link between 4500 and ie3000 the debugging output shows that the ie3000 (10.20.34.2) delete the networks learned by OSPF. SOmebody has an idea of what is exactly the problem. ... View more
