Enabling Ldp Auto-Configuration In An Area For A Specified Ospf Instance - Cisco CRS Configuration Manual

Implementing MPLS Label Distribution Protocol

Enabling LDP Auto-Configuration in an Area for a Specified OSPF Instance

Perform this task to enable IGP auto-configuration in a defined area with a specified OSPF process name.
You can disable auto-configuration on a per-interface basis. This lets LDP enable all IGP interfaces except
those that are explicitly disabled.
This feature is supported for IPv4 unicast family in default VRF only.
