Enabling MLDP MoFRR

Perform this task to enable multicast only fast reroute (MoFRR) support in MPLS MLDP.
SUMMARY STEPS
1. configure
2. mpls ldp
3. mldp
4. address-family ipv4
5. mofrr
6. end or commit
Purpose
Enables the make-before-break feature.
(Optional) Configures the MBB forwarding delay in seconds. Range
is 0 to 600.
• 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.
