Parameter value: Length of time for the Keepalive timer, in the range 1 to 65,535 seconds.
Description Use the
mpls ldp timer keepalive-hold command to set the keepalive timers.
Use the undo mpls ldp timer keepalive-hold command to restore the
defaults.
In interface view, you configure the link Keepalive timer; in MPLS LDP remote peer
view, you configure the targeted Keepalive timer.
By default, both the link Keepalive timer and targeted Keepalive timer are set to
45 seconds.

CAUTION:
■ If more than one link with LDP enabled exists between two LSRs when, for
example, the two LSRs are connected through multiple interfaces, the
Keepalive timers of all the links must be identical for sessions to be stable.
■ Changing the values of the Keepalive timers will cause existing LDP sessions to
be reestablished.
Example # Set the link Keepalive timer for local sessions to 50 seconds on interface
Ethernet 1/0.
