Yes, both 'match ip address' and 'set ip next-hop' are handled in hardware
on the Sup222.

That's the idea. There was a DDTS, however, where the second choice wasn't
programmed in hardware, but was instead handled in software, I think. I
don't have the DDTS number handy, and am not totally sure about the details.
You may want to look this up.
