This section describes how to configure a device as the egress of an MPLS-in-UDP tunnel.
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.
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.
Before configuring a device as the egress of an MPLS-in-UDP tunnel, configure an SR-MPLS tunnel.
The system view is displayed.
The MPLS-in-UDP capability is enabled, and the MPLS-in-UDP view is displayed.
A destination IP address is specified for an IP address verification list.
A source IP address is specified for an IP address verification list.
The device is enabled to verify the source IP address mapped to the specified destination IP address.
Source address verification secures MPLS-in-UDP tunnels. After the validate-list enable command is run and the device receives an MPLS-in-UDP packet, the device verifies the source IP address. The device discards the packet if the verification fails.
The configuration is committed.
