Description
Using the mpls ldp timer command, you can set the duration of a Hello timer.
Using the undo mpls ldp timer command, you can restore the default value.
Timeout of Hello timer means that the adjacency relation with the peer is down,
while timeout of hold timer means that the session relation with the peer is down.
Generally speaking, the default value can be directly adopted. In special cases, it
needs to be modified according to requirements. It should be noted that the
modification of hello parameter may cause the original session to be recreated and
the LSP created on the basis of this session will also be deleted and needs to be
recreated.
In general, the transmission interval of hello/keepalive packets is one-third of the
hold time of hello/session timer.
For the related commands, see mpls ldp and mpls ldp enable.
