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
Enters interface configuration mode for the LDP protocol.
interface type interface-path-id
Example:
RP/0/RP0/CPU0:router(config-ldp)# interface
Step 3
POS 0/1/0/0
RP/0/RP0/CPU0:router(config-ldp-if)#
Exits the current configuration mode.exit
Example:
RP/0/RP0/CPU0:router(config-ldp-if)# exit
