Configuring Traffic-Engineering Resources

You can configure the following resource-related information about an MPLS interface (at either the major interface or subinterface level):

Bandwidth—Total bandwidth that can be reserved on the interface
Flooding thresholds—Sets of absolute percentages of total reservable bandwidth that trigger the new bandwidth value to be flooded throughout the network; flooding is triggered when bandwidth increases past any up threshold value or decreases past any down threshold value
Flooding frequency—Periodicity with which the bandwidth value is flooded, apart from any flooding due to value changes
Administrative weight—Weight assigned to the interface that supersedes any assigned by the IGP
Attribute flags—32-bit value that assigns the interface to a resource class and enables a tunnel to discriminate among interfaces by matching against tunnel affinity bits
