You'll kinda need to throw away your 7200.

If you're using an NPE-G2 then you'll have three Gig-E interfaces which don't cross the PCI
backplane, but if you use two of them to talk to transit (in, for instance, an LACP bundle) then you're
going to need two of them to talk to your core.  

That'll probably mean a PA-GE port adaptor.  Driving that at 600 Mbps will probably swamp the
poor 7200.

Get a gruntier box.  10 Gbps isn't expensive anymore (it's way cheaper than 1 Gbps was when
the industry started adopting it), and the 7200 series was end-of-lifed years ago.
