## AI overview

A networking challenge to build an MPLS-based transit network with BGP at the edges but no BGP running on core routers. It proposes using SR/MPLS instead of LDP and implementing the design on Arista vEOS and FRR containers.

## Source excerpt

Here's another challenge for BGP aficionados: build an MPLS-based transit network without BGP running on core routers. That should be an easy task if you configured MPLS in the past, so try to spice it up a bit: Use SR/MPLS instead of LDP Do it on a platform you're not familiar with (hint: Arista vEOS is a bit different from Cisco IOS) Try to get it running on FRR containers.
