Parameters
time: Specifies the maximum notification delay in the range of 60 to 600 seconds.
Usage guidelines
After LDP restarts or an active/standby switchover occurs, LDP convergence begins after a period of
time. If LDP immediately notifies IGP of all the current LDP IGP synchronization status, and updates
the status after LDP convergence, IGP might frequently process the status, and the cost might
increase.
The notification delay mechanism for an LDP restart or an active/standby switchover provides a
notification delay of LDP process levels. When LDP restarts or an active/standby switchover occurs,
this mechanism enables LDP to wait a period of time till LDP recovers to the status before the restart
or switchover, and then notify IGP of the LDP IGP synchronization status in bulk. If LDP does not
recover to the status before the restart or switchover when the maximum delay set by this command
expires, LDP immediately notifies IGP of the LDP IGP synchronization status in bulk.
Examples
# Configure the maximum notification delay as 300 seconds.
