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 specific
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
Enables an auto-tunnel backup feature for
the specified interface.
auto-tunnel backup
Example:
RP/0/RP0/CPU0:router(config-mpls-te-if)# auto-tunnel backup
Step 4
You cannot configure the static
backup on the similar link.
Note
Configures attribute-set template for
auto-tunnel backup tunnels.
attribute-set attribute-set-name
Example:
RP/0/RP0/CPU0:router(config-mpls-te-if-auto-backup)#attribute-set
