Is MPLS dataplane forwarding (label swapping/popping) supported in CEOS?  I’ve been trying to mock up an L3 leaf-and-spine using MPLS for transport (to avoid the need to multiple back-to-back VRFs on all the leaf-spine peerings and the requisite un-supported routed subinterfaces), and everything *seems* to work fine up to the spine actually forwarding an MPLS frame.   (I can see the frames come in with a two-label stack, and what looks like a valid match in the lfib, but the frame never seems to pushed out the egress interface.)

Hello Mencken,

Currently cEOS-lab doesn’t support the MPLS data plane forwarding, we are going to add this feature in our upcoming releases. But for the testing you are trying to do, May I suggest using vEOS-lab ? It is a bit bigger resource footprint but should work perfectly fine for the testing you are trying to do. Let me know if you notice any problem with the vEOS-lab on this part.

Thanks Lokesh!  Very-much appreciated.  I've verified functionality on vEOS, but I had my hat hung on running simulations on generic AWS EC2 instances which don't have the nested virtualization support to make vEOS viable.  I'll re-cast my plans for an alternate compute platform.

Is MPLS dataplane supported now in cEOS-lab-4.27.0F? I would like to build a segment routing lab using containerlab.
