Configure the Periodic Flooding Timer

All MPLS interfaces are checked every three minutes by default. TE advertisements are triggered when there is a difference in the available bandwidth and advertised available bandwidth.

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.

Enable the device and configure the terminal to the global configuration mode.
```
device>enable
device# configure terminal
```
Enable the MPLS router.
```
device(config)# router mpls
```
Configure policy parameters.
```
device(config-mpls)# policy
```
Set the interval for RSVP TE periodic flooding.
```
device(config-mpls-policy)# rsvp-periodic-flooding-timer 240
```
In this example, the timer is set to 240 seconds (four minutes).

Example

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
