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 this command removes the sub-set of the configured threshold values.
Use the rsvp-flooding-threshold command at the MPLS interface level as shown below to set the
reserved bandwidth threshold.
Brocade(config)# router mpls
Brocade(config-mpls)# mpls-interface ethernet 1/1
Brocade(config-mpls-if-e100-1/1)# rsvp-flooding-threshold up 10 20 30 40 50 55 60
65 70 85 90 92 93 94 95 96 97 98 99 100
Brocade(config-mpls-if-e100-1/1)# 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
Brocade(config-mpls-if-e100-1/1)#
In the example below, the UP thresholds contain 10, 50, 55, 95, 96, 97, 98 and 100. The DOWN
thresholds contain 50, 40, 30, 20 and 10.
Brocade(config)# router mpls
Brocade(config-mpls)# mpls-interface ethernet 1/1
Brocade(config-mpls-if-e100-1/1)# rsvp-flooding-threshold up 10 50 55 95
Brocade(config-mpls-if-e100-1/1)# rsvp-flooding-threshold up 96 97 98 99 100
Brocade(config-mpls-if-e100-1/1)# rsvp-flooding-threshold down 50 40
Brocade(config-mpls-if-e100-1/1)# rsvp-flooding-threshold down 30 20 10
Brocade(config-mpls-if-e100-1/1)#
Syntax: [no] rsvp-flooding-threshold [up|down][percentage]*
Use the [no] form of this command to remove the RSVP TE flooding threshold configuration.
The down option sets the thresholds for decreased resource availability. Valid values are from 0 to
99. The default values for down is 100, 99, 98, 97, 96, 95, 90, 85, 80, 75, 60, 45, 30, 15.
The up option sets the thresholds for increased resource availability. Valid values are from 1 to
100. The default values for up is 15, 30, 45, 60, 75, 80, 85, 90, 95, 97, 98, 99, 100.
The percentage option sets the bandwidth threshold level.
"*” represents multiple percent values can be given. A minimum one percentage value is required.
Percentage values can be given in any order and are internally sorted before storing.
Configuring the periodic flooding timer
All MPLS interfaces are checked every three minutes by default. TE advertisements are triggered
when there is a difference in the available bandwidth and advertised available bandwidth.
