The mpls te manual-flooding command allows an interface on a TE tunnel to flood changed bandwidth if the bandwidth is changed.
By default, an interface on a TE tunnel floods bandwidth only after the changed bandwidth reaches the flood threshold, The default flooding threshold is 10% of the remaining bandwidth of the current interface.
Usage Scenario
After an interface on a tunnel reserves or releases bandwidth, the interface floods bandwidth information only after the changed bandwidth reaches the flood threshold. The mpls te manual-flooding command allows an interface to flood the changed bandwidth over a network immediately if the bandwidth is changed.
