Hello,

Co-existence of multiple dataplane technologies to carry BESS services is
useful for among others migration of one dataplane technology to another
(e.g. (SR)MPLS to SRv6).

Can co-existence be achieved without changing current specifications, or
would it require extensions / changes? For example as proposed in
draft-ls-bess-srv6-mpls-coexisting-vpn.

I was thinking maybe the BGP ADD-PATH capability could be leveraged to
achieve co-existence.

Would it be of interest to document co-existence cases and solutions?

Thanks!

cheers,
  Eduard
