Tony, We're generally not switching IP on the bare metal even now. As often as not we're switching ethernet frames, MPLS packets or sonet frames. Map-encap changes the adjacency of IP nodes in the network but it doesn't fundamentally change the switching model. Right? Regards. Bill Herrin -- William D. Herrin ................
