[c-nsp] All OSPF adj/neigh flapping every 30-35 minutes

[Rodney Dunn]

'debug ip ospf packet hello' and see if the hellos are being lost.

You can couple that with a 'debug ip packet <ACL>' where the ACL
matches on ospf packets between the peers. This brings you down
from OSPF to the ip packet layer to see if the drops are lower down
the stack.

The logs on the routers do not show any other events; no physical layer issues. Is there a command that will tell me what's causing these neighbors to go up/down?
