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.
interface tunnel-te tunnel-id
Example:
RP/0/RP0/CPU0:router# interface tunnel-te 1
Step 2
Enables fast reroute.fast-reroute
Example:
RP/0/RP0/CPU0:router(config-if)# fast-reroute
Step 3
Exits the current configuration mode.exit
Example:
RP/0/RP0/CPU0:router(config-if)# exit
Step 4
Enters MPLS-TE configuration mode.mpls traffic-eng
Example:
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
Step 5
RP/0/RP0/CPU0:router(config-mpls-te)#
Enables traffic engineering on a particular interface on the
originating node.
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-mpls-te)# interface
Step 6
pos0/6/0/0
RP/0/RP0/CPU0:router(config-mpls-te-if)#
