Re: MPLS LDP Session Protection

Hi,

First statement is correct. i.e LDP Targeted Hello Adjacency to exist
indefinitely following the loss of an LDP Link Hello Adjacency. But you can
change this timer. Also when LDP Link Adjacency fails, if the LDP peer is
still reachable through IP, then only the LDP session stays up, because the
LDP Targeted Hello Adjacency still exists between the routers

Thanks,
