I'd say yes, though I'm not sure how it compares to a VXR with NPE-G1...it
probably doesn't.  Keep in mind, there's no real gigE for the 7500.
Sure, there are GEIP and GEIP+, but both are a waste of money if you want
gigE because you have gigE traffic and aren't simply looking to terminate
a few FE worth of traffic from the 7500 into a switch that has no FE
ports.

I still say keep the VXRs around for terminating WAN interfaces (T1, DS3),
and get a 6500 for the FEs.  Don't waste time on the 7500 unless you're
prepared to go straight to RSP8 and VIP4s instead of the much cheaper
RSP4s and VIP2s.
