Use the rsvp-periodic-flooding-timer command to set the interval for periodic flooding. The interval is set in seconds. To set the interval as 240 which triggers periodic flooding every four minutes, complete the following steps.
device>enable device# configure terminal
device(config)# router mpls
device(config-mpls)# policy
device(config-mpls-policy)# rsvp-periodic-flooding-timer 240
The following example shows how to set the periodic flooding timer. In this example, the time is set for 240 seconds (four minutes).
device>enable device# configure terminal device(config)# router mpls device(config-mpls)# policy device(config-mpls-policy)# rsvp-periodic-flooding-timer 240 device(config-mpls-policy)# no rsvp-periodic-flooding-timer
