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.
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.
