Description: The UDP Discovery Port for LDP. The default value is the well-known value for this port.

What is mplsLdpEntityWellKnownUdpDiscoveryPort?

The UDP port on which this LDP entity sends and listens for Hello discovery messages, defaulting to 646 as specified in RFC 3036. Like its TCP counterpart, this is left at the well-known value in virtually all deployments; changing it would break basic and extended discovery with standard-compliant peers.
