Command History
Usage Guidelines Use this command to set the interval for periodic flooding of traffic engineering (TE) topology
i
nformation.
Changes in the Multiprotocol Label Switching (MPLS) TE topology database are flooded by the link
st
ate Interior Gateway Protocol (IGP). Some changes, such as those to link status (up/down) or
configured parameters, trigger immediate flooding. Other changes are considered less urgent and are
flooded periodically. For example, changes to the amount of link bandwidth allocated to TE tunnels are
flooded periodically unless the change causes the bandwidth to cross a configurable threshold.
Examples The following example sets the interval length for periodic flooding to advertise flooding changes to
120 seconds.
Router(config)# mpls traffic-eng timers periodic-flooding 120
