Re: [j-nsp] OSPF neighbor Down :: without reason





This looks like a physical layer problem.  Maybe not a link flap per se 
but some sort of media issue.  I'm not familiar with the inactive timer 
though so I don't know what the first message means exactly.  The one-way 
message seems kind of odd as well.  Your neighbor declared you dead before 
you did the same.  The route only noticed because the neighbor sent a 
hello without it's router id in the list of known routers.  What kind of 
link is connecting the two routers?  Is it frame-relay or sonet?  It seems 
like there was a link failure that didn't lead to an interface flap.  Are 
there any errors on your sh int <> extensive?  Also how often does this 
happen.
