Usage guidelines

When the reservable bandwidth of a link changes, IGP floods the link TE information to notify network devices of the change. You can use the mpls te bandwidth change thresholds command to configure IGP to flood only significant bandwidth changes of a link to prevent excessive IGP flooding. The bandwidth changes that cannot trigger immediate flooding are flooded at the interval configured by the link-management periodic-flooding timer command.

If you set the interval to 0, the periodical flooding feature is disabled. If you set the interval to a value less than 30 seconds (1 to 29 seconds), the device automatically sets the interval to 30 seconds.

After you execute this command, the configured interval takes effect immediately.

Examples

# Configure IGP to flood TE information every 100 seconds.
