DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters MPLS LDP configuration mode.mpls ldp
Example:
RP/0/RP0/CPU0:router(config)# mpls ldp
Step 2
(Optional) Specifies a non-default VRF.
[vrf vrf-name] router-id lsr-id
Step 3
Example:
RP/0/RP0/CPU0:router(config-ldp)# router-id
192.168.70.1
Specifies the router ID of the local node.
In Cisco IOS XR software, the router ID is specified as an interface
name or IP address or LSR ID. By default, LDP uses the global
router ID (configured by global router ID process).
Enters interface configuration mode for the LDP protocol.
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ldp)# interface
tunnel-te 12001
Step 4
commit—Saves the configuration changes and remains within the
configuration session.
Use the commit or end command.
Step 5
end—Prompts user to take one of these actions:
