I came in late so forgive me if I state something others have said. If
there are more than one pVCs on the interface, you are correct, however
if there is only one pvc and the remote end goes down, then I believe
the local end will show aa line protocol down.
In addition, even if the local interface line protocol stays up, if you
are using dynamic routing protocols, the far end reachability over the
local interface will cease, with availability now over the other router,
it will become the active router.
