OSPF

Will OSPF detect and weight a link that is down 'service-wise'? I think most routing protocols will detect when a interface is down and weight the route. However what if the interface is up but traffic can't go thru due to some misconfiguration or problem on the distant end.

Re: OSPF

OSPF has hello mechanism between neighbors. So, when service is down, but interface is up, OSPF router wont be able to send the hello, and this will cause routers to wait until dead time (default is 40 seconds in broadcast/p-p networks, and 120 seconds in NBMA), Once this timer expires, it will detect the failure..
