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?
Short and simple answer: No.
What about 7600 and re-circulation? I don't remember exactly what is what,
but wouldn't there be cases where you'd get 15Mpps with regular CEF and
30Mpps with label switching (LSR) ?
There is definitely an advantage while doing 6PE compared to regular
CEF-switching on GSR with engine2, 4 and 6 linecards (LSR again).
But generally I agree that there is little reason to go MPLS...
