DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters MPLS-TE configuration mode.mpls traffic-eng
Example:
RP/0/RP0/CPU0:router(config)# mpls traffic-eng
Step 2
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
POS 0/6/0/0
Step 3
Sets the backup path for the primary tunnel outgoing
interface.
backup-path tunnel-te tunnel-number
Example:
RP/0/RP0/CPU0:router(config-mpls-te)#
backup-path tunnel-te 2
