I’m having troubles with the function BFD over OSPF. It keep stalled in init state forever. The other peers can’t see router in 7.21rc2. In other versions of 7.21 beta or release candidate the problem are the same. The other peer are in 7.20.3. If I keep all in 7.20.3 all is normal and the sessions are established.
Sorry for my poor English. A spanish boy in this place.
Best Regards.
