MPLS Traffic Engineering Flooding Reduction Interface Specific Configuration

The rsvp-flooding-threshold command can be executed multiple times for the same interface. The threshold values are added to the existing set of values for the interface. Previously configured values are not overwritten. The interface specific configuration overrides the global configuration. Using the no form of the command removes the sub-set of the configured threshold values.

Complete the following steps using the rsvp-flooding-threshold command at the MPLS interface level to set the reserved bandwidth threshold.

  1. Enable device and configure the terminal to the global configuration mode.
    device# configure
  2. Enable the MPLS router.
    device(config)# router mpls 
  3. Enable MPLS-capable interfaces.
    device(config-router-mpls)# mpls-interface ethernet 0/1
    In this example, ethernet interface 0/1 is enabled.
  4. Enable LDP parameters.
    device(config-mpls-if-eth-0/1)# rsvp
  5. Enable RSVP triggered traffic engineering LSA flooding reduction. Use the up option. This triggers the bandwidth percentage to go up when the bandwidth is increased.
    device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold up 10 20 30 40 50 55 60
    65 70 85 90 92 93 94 95 96 97 98 99 100
  6. Enable RSVP triggered traffic engineering LSA flooding reduction. Use the down option. This triggers the bandwidth percentage to go down when the bandwidth is decreased.
    device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold down 99 98 97 96 95 94
    93 92 91 90 85 80 75 70 65 60 55 50 40 30 20 10

the following example shows how to set the reserved bandwidth threshold at the interface level.

device# configure
device(config)# router mpls
device(config-mpls)# mpls-interface ethernet 0/1
device(config-mpls-if-eth-0/1)# rsvp
device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold up 10 20 30 40 50 55 60
65 70 85 90 92 93 94 95 96 97 98 99 100
device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold down 99 98 97 96 95 94
93 92 91 90 85 80 75 70 65 60 55 50 40 30 20 10
device(config-mpls-if-eth-0/1-rsvp)#

In the following example, the UP thresholds contain 10, 50, 55, 95, 96, 97, 98, and 100. The DOWN thresholds contain 50, 40, 30, 20, and 10.

device# configure
device(config)# router mpls
device(config-mpls)# mpls-interface ethernet 0/1
device(config-mpls-if-eth-0/1)# rsvp
device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold up 10 50 55 95
device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold up 96 97 98 99 100
device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold down 50 40
device(config-mpls-if-eth-0/1-rsvp)# rsvp-flooding-threshold down 30 20 10
