[c-nsp] 7200 GRE tunnel CPU load

[Dan Benson]

I have a few 7200's out there in the field running GRE tunnels between 
one another with the destinations set to the external (Public) interface 
IP.  In the world of the 7600/6500-sup720 when you build GRE tunnels you 
should assign an unique IP to a loopback for each end of the tunnel in 
order to have the packets hardware switched.  From what I knew the 7200 
cannot hardware switch packets over a GRE tunnel but I figured I would 
write to ask before I put the effort into trying. I thank you all for 
the your help in advance.. //db
