Have anybody encounter a problem when an ospf neighbourship is being stuck in the EXSTART/DR ?

If yes how it is possible to fix this problem.

Thanks in advance

Re: OSPF problem

Lukas,

Here is a link that might help. Is this between a router and a switch? It might be MTU mismatch.

Re: OSPF problem

I have checked it but everything seems to be ok.

Both routers can ping each other, the MTU sizes are the same, both are connected to BROADCAST network and there is no ACL between them.

Re: OSPF problem

Generally Exstart- Exchange problems are due to mismatch, you may refer this link for similar problems & solution:
