[c-nsp] ICMP and SUP720

[Ronen Isaac]

Thanks Mikael,
That makes me feel like I am on the right track.  Just out of curiosity
do you know how ICMP is handled on the 720?  Is it still done in
software?  

Thanks again!

Kind Regards,

Yes, the Sup720 is a good choice. If you need full internet tables, be 
sure to get the XL version.

We opted for swap of our BD blades to get ICMP Fast path on our extremes

as well (they do this as of approximately a year), it has worked very 
well. We use BD, Alpine and 48si:s for distribution and Sup720 7600 or
GSR 
for core.
