Cisco CRS Configuration Guide

Enabling MLDP
Perform this task to enable Multicast Label Distribution Protocol (MLDP) in MPLS LDP.
SUMMARY STEPS
1.
configure
2.
mpls ldp
3.
mldp
4.
end or commit
DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters the MPLS LDP configuration mode.mpls ldp
Example:
RP/0/RP0/CPU0:router(config)# mpls ldp
Step 2
Enables MLDP.mldp
Example:
RP/0/RP0/CPU0:router(config-ldp)# mldp
RP/0/RP0/CPU0:router(config-ldp-mldp)#
Step 3
end or commit
Step 4
•
When you issue the end command, the system prompts you to
commit changes:
Uncommitted changes found, commit them before
Example:
RP/0/RP/0/RP0/CPU0:router
(config-ldp-mldp)# end
exiting(yes/no/cancel)?
[cancel]:
or
RP/0/RP/0/RP0/CPU0:router
(config-ldp-mldp)# commit
•
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.
