DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Configures an MPLS-TE tunnel interface and enables traffic
engineering on a particular interface on the originating node.
interface tunnel-te tunnel-id
Example:
RP/0/RP0/CPU0:router(config)# interface
Step 2
tunnel-te 6
RP/0/RP0/CPU0:router(config-if)#
Configures automatic bandwidth on a tunnel interface and enters
MPLS-TE automatic bandwidth interface configuration mode.
auto-bw
Example:
RP/0/RP0/CPU0:router(config-if)# auto-bw
Step 3
RP/0/RP0/CPU0:router(config-if-tunte-autobw)#
Configures the application frequency in minutes for the applicable
tunnel.
application minutes
Example:
RP/0/RP0/CPU0:router(config-if-tunte-autobw)#
Step 4
minutes
Frequency in minutes for the automatic bandwidth
application. Range is from 5 to 10080 (7 days). The default
value is 1440 (24 hours).
