You can execute the mpls ldp igp sync disable command to disable LDP-IGP synchronization on
interfaces where LDP-IGP synchronization is not required.
Configuring LDP-OSPF synchronization
LDP-IGP synchronization is not supported for an OSPF process and its OSPF areas if the OSPF process
belongs to a VPN instance.
To configure LDP-OSPF synchronization for an OSPF process:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id
router-id ] *
N/A
3. Enable LDP-OSPF
synchronization.
mpls ldp sync
By default, LDP-OSPF synchronization
is disabled.
4. Return to system view. quit N/A
5. Enter interface view.
interface interface-type
interface-number
N/A
6. (Optional.) Disable LDP-IGP
synchronization on the
interface.
mpls ldp igp sync disable
By default, LDP-IGP synchronization is
not disabled on an interface.
7. Return to system view. quit N/A
8. Enter LDP view. mpls ldp N/A
9. (Optional.) Set the delay for
LDP to notify IGP of the LDP
convergence.
igp sync delay time
By default, LDP immediately notifies
IGP of the LDP convergence
completion.
10. (Optional.) Set the maximum
delay for LDP to notify IGP of
the LDP-IGP synchronization
status after an LDP restart or
active/standby switchover.
igp sync delay on-restart time
By default, the maximum notification
delay is 90 seconds.
To configure LDP-OSPF synchronization for an OSPF area:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id

N/A
3. Enter area view. area area-id N/A
4. Enable LDP-OSPF
synchronization.
mpls ldp sync
By default, LDP-OSPF
synchronization is disabled.
5. Return to system view. quit N/A
6. Enter interface view.
