## AI overview

A hands-on tutorial showing how to configure and inspect SR-MPLS over OSPFv2 with netlab. It explains the OSPFv2 opaque LSAs used to advertise SR-MPLS information and notes that the resulting MPLS forwarding table matches the comparable IS-IS example.

## Source excerpt

I started my part of the Segment Routing workshop @ ITNOG10 exploring SR-MPLS with IS-IS (simple SR-MPLS, dual-stack SR-MPLS, SR-MPLS over unnumbered IPv4 interfaces). Next step: let's change the routing protocol to OSPF while using the same network topology: Read more ...
