[c-nsp] High Availability PoP Design

[David J. Hughes]

Just a side note.  This issue isn't a problem if the routing devices 
are L3 switches (several ports in a vlan, SVI being the L3 target).  
Seeing as a 6503/Sup32 bundle is about 30% cheaper than a 7206/NPE-G1 
bundle I imagine we may see more people deploying devices like this at 
the border.  They are certainly better at handling DOS scenarios.

I had a "handy sup comparison" chart bookmarked but can't find it right 
now.  I assume that the Sup32 can handle a full table?
