Parameter
hello hello-holdtime: Specifies the hold time (i.e. timeout time) of the Hello hold
timer, in the range of 6 to 65535 (seconds). By default it is 15 seconds.
session-hold session-holdtime: Specifies the time interval for Session hold timer
to send a session packet, in the range of 1 to 65535 (seconds). By default it is 60
seconds.
targeted-hello: Specifies the hold time (i.e. timeout time) of the Targeted-hello
hold timer, in the range of 1 to 65535 (seconds). By default holdtime is 45 seconds
and interval is 13 seconds.
targeted-session-hold: Specifies the time interval for Targeted-session hold timer
to send a session packet, in the range of 1 to 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.
