Configuring MPLS LDP IS-IS Synchronization
This task explains how to enable Multiprotocol Label Switching (MPLS) Label Distribution Protocol
(LDP) IS-IS synchronization. MPLS LDP synchronization can be enabled for an address family under
interface configuration mode. Only IPv4 unicast address family is supported. This task is optional.
SUMMARY STEPS
1. configure
2. router isis instance-id
3. interface type instance
4. address-family ipv4 unicast
5. mpls ldp sync [level {1 | 2}]
6. end

Step 10
set-attached-bit
Example:
RP/0/RP0/CPU0:router(config-isis-af)#
set-attached-bit
(Optional) Configures an IS-IS instance with an attached bit
in the Level 1 LSP.
Step 11

commit
Example:
RP/0/RP0/CPU0:router(config-isis-af)# end

RP/0/RP0/CPU0:router(config-isis-af)# commit
Saves configuration changes.
• 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.
