[c-nsp] route ipv6 in software

[Ethern M.C. Lin]

I have experience of software IPv6 routing on 7513,
and I try the IOS version started from 12.2(T) quite
early. Now I use the 12.3(14)T1.

I also tried the 6509 for SUP2 a year ago, but now
we have upgraded to SUP720 w/ 12.2(18)SXE. 
It provides better in performance and functionality.

But I think this performance is not the critical problem
in currently, because the IPv6 traffic is not large enough 
as IPv4.

And you can use IPv6 CEF if support in your IOS, I think
that will be better in performance.

Regards,

Ethern
