If you issue the mpls ldp session protection command without the duration keyword, then session
protection is enabled for 86400 seconds (24 hours) meaning that the LDP Targeted Hello Adjacency is
retained for 24 hours after a link is lost. This is the default timeout.
If you issue the mpls ldp session protection duration infinite command, then session protection is
enabled forever meaning that the LDP Targeted Hello Adjacency is retained forever after a link is lost.
If you issue the mpls l
dp session protection duration seconds command, then session protection is
enabled for the number of seconds indicated meaning that the LDP Targeted Hello Adjacency is retained
for that amount of time. For example, if you issued mpls ldp session protection duration 100, then the
LDP Targeted Hello Adjacency is retained for 100 seconds after a link is lost.
