To clarify what I meant when I said "L2 bridge", I was actually referring to plain IPv6 routers that operate on the RFC2463 encapsulation header *at a layer below IP*. These routers run plain old BGP and exchange SLA routes. But again, this happens at a layer below the IP layer seen by the transports and applications. > I think I understand what you are trying to do. I just don’t think this will work, some problems are best not solved at L3. As I outlined > below, I think the transport layer (and probably application layer) will also need to be involved. We are not solving this at L3; we are solving it at the adaptation layer below the IP layer seen by the transports and applications. It is called the OMNI Adaptation Layer. And, if you want to see it working I would be happy to demonstrate with real running code.
