SR-MPLS over Unnumbered Interfaces

After the simple SR-MPLS demo and the dual-stack SR-MPLS setup , it was time for the next obvious question: Does SR-MPLS work over unnumbered IPv4 interfaces 1 , assuming the implementation of the underlying routing protocol supports them? Of course it does; let&rsquo;s go through the details, using the same topology I used throughout the Segment Routing workshop @ ITNOG10. Read more &hellip;
