The mpls-in-udp command enables MPLS in UDP globally on a local node and displays the MPLS-in-UDP view.
The undo mpls-in-udp command disables MPLS in UDP.
By default, MPLS in UDP is disabled on a node.
Usage Scenario
MPLS in UDP is a DCN overlay technology that encapsulates MPLS packets (or SR MPLS packets) into UDP packets to traverse through some networks that do not support MPLS or SR MPLS.
Precautions
A device can be configured only as the egress of an MPLS-in-UDP tunnel to properly process MPLS-in-UDP packets. Running the mpls-in-udp command does not trigger the establishment of an MPLS-in-UDP tunnel.
