[c-nsp] 12410 or 7690-S for BGP transits

[William Jackson]

Its more a case of IOS features and platform capabilities than port
densities and costs, as both platforms can have high performance and
port densities.

Like I mentioned before, I would like the uptime to be as good as
possible, with regards to software upgrades and self healing in event of
bugs etc.

We are using BGP and OSPF on our current boxes so would expect to keep
the same protocols.

thanks

Generally for BGP peering you don't need all the fancy features that  
the SIP-600 gives you, it's complete overkill.  You are better off  
just getting a 7600 with normal LAN linecards, otherwise your per-port  
cost is going to be enormous.
