Hi Bill,
|Huh? Your point escapes me. | |In production we use MPLS to support both core routing (where the RIB |load on intermediate routers is reduced) . We also use it to provide |virtual circuits, such as virtual ethernets between one customer |location and another. | |The latter use has nothing whatsoever to do with IP internetworking. |It's just another function that MPLS happens to be good for. My |routers can also implement frame relay switching and provide a PVC |between two customer locations. So what? | |Why would map-encap for Internet core routing have any impact at all |on the use of MPLS for virtual circuits? You're right, you're missing my point. ;-) The point is that once you decide to run the network on top of virtual circuits, that means that you can no longer do packet switching on the 'bare metal'. In some sense, this is an admission that IP is insufficient. It needs an underlying layer of support before it can be run. I would much rather see IP be self-sufficient.
