## AI overview

This tutorial demonstrates a multivendor SR-MPLS network built with netlab using Arista EOS, FRRouting, and SR Linux. It explains vendor-specific Segment Routing Global Block ranges, prefix segments, and MPLS LFIB label swapping, then outlines how to launch the lab through GitHub Codespaces.

## Source excerpt

Summer is almost over, and it's time to resume regular programming with the next example from the Segment Routing workshop I had at ITNOG10: multi-vendor SR-MPLS. I used the same lab topology as in the previous examples but deployed Arista EOS on PE1, FRRouting on P, and SR Linux on PE21 Read more ...
