Parameter
hello hello-holdtime: Hold time (i.e. timeout time) of the Hello hold timer, in the range of
6~65535 (seconds). By default it is 15 seconds.
session-hold session-holdtime: Time interval for Session hold timer to send a session
packet, in the range of 1~65535 (seconds). By default it is 60 seconds.
targeted-hello: Hold time (i.e. timeout time) of the Targeted-hello hold timer, in the
range of 1~65535 (seconds). By default holdtime is 45 seconds and interval is 13
seconds.
targeted-session-hold: Time interval for Targeted-session hold timer to send a
session packet, in the range of 1~65535 (seconds). By default holdtime is 60 seconds
and interval is 24 seconds.
holdtime: Time interval for the hold timer.
interval: Time interval to send a Keepalive packet.
Description
Use the mpls ldp timer command to set the hold time for the Hello hold timer and
Session hold timer.
Use the undo mpls ldp timer command to restore the default values.
The timeout of the Hello hold timer means that the adjacency with the peer goes down;
the timeout of the Session hold timer means the session with the peer goes down.
targeted-hello interval refers to the time interval to send a targeted-hello packet. It
cannot be greater than (targeted-hello holdtime) × 0.3, so the maximum value is
65535× 0.3 = 19660.5.
targeted-session-hold interval refers to the time interval to send a Keepalive packet. It
cannot be greater than (targeted-session-hold holdtime) × 0.4.
In general, the time interval to send a hello/keepalive packet is one third of the hold time
of Hello/Session hold timer.
You can usually use the default values if not in special cases, Note that you must reset
the session to validate new values if you do modify these timer parameters.
Related command: mpls ldp and mpls ldp enable.
Example
# Modify the hold time of the Hello timer to 30 seconds.
