I support the draft and agree this is very useful for cloud native
environments.

I think the main use of this feature is for DC fabric extension to compute
nodes and now as well Kubernetes microservices cloud native
containerization or router in a container.

Just about every router vendor and ONF disaggregation vendor has a
container version of router such as Cisco’s XRD, Juniper cRPD, SONiC,
Nokia, Arista etc which gives you both control plane and data plane to
front and provide CNI networking for K8 Kubernetes microservices.

As well as you have all the Open BGP versions FRR, BIRD, Quagga, ExaBGP etc
that  give you the BGP control plane to advertise routes using Linux data
plane.

https://containerlab.dev/manual/kinds/

So this version feature is really for cloud native compute layer NFV - VNF,
CNF,  and not really for PNF  physical hardware based internet routers or
switches.

I can see a lot of value in this draft and I support making a WG document
versus independent stream based on the massive proliferation of distributed
cloud native edge computing software based environments.

Kind Regards

Gyan
