[c-nsp] MPLS vs CEF

[John Neiberger]

I'm curious about something. Let's say a company has a large internal
network that needs to move a lot of data quickly on a regular basis,
but just within the enterprise. If they already have CEF enabled on
all routers, is there any performance gain to be had by then enabling
MPLS and switching based on labels instead of using CEF alone? I'm
just learning MPLS and I really have no reference for how it performs
compared to CEF alone.
