MPLS support Arista cEOS #1267

Closed ubaumann closed 3 months ago

Does the new image ceos:4.32.1F support MPLS now?

I was aware of issues with the MPLS data plane on cEOS and wanted to know if I could make the control plane work for L3VPN. After reading this long discussion https://github.com/srl-labs/containerlab/discussions/807, I thought I should also try to make the data plane work. And, of course, I used the newest image.

I needed to do more tests, but it turned out that I could do a small "pe" - "p" - "pe" VPN setup without any big issues. I need to do more tests, but so far it looks like the newest container works well for my use case.

My setup is in the directory "netlab" here: https://github.com/NetAutLabs/mpls_l3_vpn_service (I need to clean up some stuff, but for now, it works (on Unbuntu and GitHub Codespaces)

When I want to use the mpls module from netlab I get the following message:

[ERRORS]  Errors found in topology.yml
[TYPE]    quirks: Arista cEOS (edge1) does not support MPLS. Use vEOS VM with libvirt provider
[TYPE]    quirks: Arista cEOS (edge2) does not support MPLS. Use vEOS VM with libvirt provider
[FATAL]   Cannot proceed beyond this point due to errors, exiting

a) Is there a way to ignore the error so I can do more testing? b) What use cases need to be tested with the new version to remove this error message? Are there any automated tests?

PS: Thanks for the great work

No idea, will test it later today or tomorrow. That would be lovely.

Remove the error message from https://github.com/ipspace/netlab/blob/dev/netsim/devices/eos.py#L25

b) What use cases need to be tested with the new version to remove this error message? Are there any automated tests?

https://github.com/ipspace/netlab/tree/dev/tests/integration/mpls

Will run them after I'm done with the crazy rabbit trails of EVPN.

Thanks a million for the poke @ubaumann -- so nice to see MPLS working in cEOS ;)
