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)#
Step 2
mpls ldp
Allows the redistribution of BGP routes into an MPLS LDP processes.

Step 3
Example:
RP/0/RP0/CPU0:router(config-ldp)#
Autonomous system numbers (ASNs) are globally unique identifiers
used to identify autonomous systems (ASs) and enable ASs to exchange
exterior routing information between neighboring ASs. A unique ASN
is allocated to each AS for use in BGP routing. ASNs are encoded as
2-byte numbers and 4-byte numbers in BGP.

end or commit
Step 4
•
When you issue the end command, the system prompts you to commit
changes:
Uncommitted changes found, commit them before
exiting(yes/no/cancel)?
[cancel]:
•
Entering yes saves configuration changes to the running configuration
file, exits the configuration session, and returns the router to EXEC mode.
•
Entering no exits the configuration session and returns the router to EXEC
mode without committing the configuration changes.
•
Entering cancel leaves the router in the current configuration session
without exiting or committing the configuration changes.
•
Use the commit command to save the configuration changes to the running
configuration file and remain within the configuration session.

Example:
RP/0/RP0/CPU0:router# show run
