DETAILED STEPS
Command or Action
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Step 2
interface tunnel-te tunnel-id
Example:
RP/0/RP0/CPU0:router(config)# interface
tunnel-te 1
Step 3
ipv4 unnumbered type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4
unnumbered Loopback0
Step 4
autoroute announce
Example:
RP/0/RP0/CPU0:router(config-if)# autoroute
announce
Step 5
exit
Example:
RP/0/RP0/CPU0:router(config-if)# exit
Purpose
Enters global configuration mode.
Enters MPLS-TE interface configuration mode.
