[c-nsp] Recommended P Nodes

[Gordon Bryan]

Hi Gert,
 
Thanks for the advice on the flavour of supervisor. That should make the 6500 option fairly cheap.
 
Definitely no full table requirements and all edge-type features will be handled by old failthful 7200VXR for now, hopefully upgrading to ASRs at some point in the future.
 
Regards
 
Gordon

6500, definitely :-) - no XL needed if this is a pure P with no full table.

Where the 6500 with Sup720 lacks is edge things (IPv6 uRPF, full netflow, 
IPv6 ACLs) and scalability to "huge" amounts of 10G - but as a P node,
you don't need the edge things, and if "some 100 Gbit/s" is good enough for
you, it will do what you want.
