## AI overview

Arista cEOS containers gained a working MPLS data plane in release 4.31.2F. After configuration changes and integration tests, netlab 1.9.0 supports MPLS on Arista cEOS, with future plans for MPLS labs in GitHub Codespaces.

## Source excerpt

Urs Baumann brought me a nice surprise last weekend. He opened a GitHub issue saying, "MPLS works on Arista cEOS containers in release 4.31.2F" and asking whether we could enable netlab to configure MPLS on cEOS containers. netlab already had MPLS configuration templates for Arista EOS but reported an error message if you tried to use MPLS with the cEOS containers because the containers did not have a working MPLS data plane. After a few configuration tweaks and a batch of integration tests later, I had the results: everything worked. You can use MPLS on Arista cEOS with netlab release 1.9.0 (right now @ 1.9.0-dev2), and I'll be able to create MPLS labs running in GitHub Codespaces in the not-too-distant future.
