MPLS is a tunnel. The idea of tagging a frame is to create a tunnel over an IP backbone. Other tunnels are IPv6 RD, GRE, and even NAT.

Ergo: MPLS is duct tape. it's like NAT.

Should we be considering replacing MPLS with simple IPv6 routing and letting the network be a network, not a bunch of tunnels over the backbone.

It's time for MPLS to be over.
