Hi Uchil,

Actually box will not be a traditional PE and I dont want to deal with RR
stuff hence customers will have redundant peerings to another PE of mine
again. eBGP serves my wishes fairly well.

I'm thinking of connecting one 7609-Sup32 to another 7609-Sup720-10G and
create 200 vrfs and eBGP peerings on both and see what happens then. I
think so sup720-10 is more than enough but I wonder the performance of
sup32.
