I have 2 links between 2 routers.
They have different OSPF costs.
The links are GE and each go via several switches so a failure at one end does not cause link to go down at the other end of the link.
If the Rx on one router fails this interface will immediately send LSAs to the other router via the remaining link.
Will the router (which is remote from the failure) immediately consider the link dead on the basis of the LSAs even though it's interface on the failed link is still up? or will it need to wait for dead time (40sec) before considering the link dead?
