[c-nsp] Cisco equivalent of juniper hardware

[Phil Bedard]

Your answers mean that the LAN-type GigE on the 7600 series is  
probably not
what you want.   Some of those cards are oversubscribed (IE, there  
are 24 GigE ports
handled by 2 10-gig ASICs.) and they don't do shaping.

While it's very new, the ES20 20-port GigE blade for the 7600 I think  
is the
cheapest option to get what you want, unless you need IPV6/mVPN/ 
4364VPN support, which adds to the cost via a license.

The GSR is probably a more mature platform to do what you want, but  
it's going to be more expensive.
