Configuring LDP-IGP synchronization

After you enable LDP-IGP synchronization for an OSPF process, OSPF area, or an IS-IS process, LDP-IGP synchronization is enabled on the OSPF process interfaces or the IS-IS process interfaces.

You can execute the mpls ldp igp sync disable command to disable LDP-IGP synchronization on interfaces where LDP-IGP synchronization is not required.

LDP-IGP synchronization protection is only applicable to an IPv4 network.
