Description

When a router fails, its neighbors do not detect the loss until the HELLO timeout expires. Routers can often detect loss-of-neighbor immediately when the links to the neighbor are closed.

A code path needs to be implemented that causes the router to detect neighbor-loss upon link loss.

This will result in much quicker recovery from failure.
