DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters MPLS-TE interface configuration mode.
interface tunnel-te tunnel-id
Example:
RP/0/RP0/CPU0:router(config)# interface
Step 2
tunnel-te 1
Assigns a source address so that forwarding can be performed
on the new tunnel.
ipv4 unnumbered type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-if)# ipv4
Step 3
unnumbered Loopback0
Enables messages that notify the neighbor nodes about the routes
that are forwarding.
autoroute announce
