I think the number of BGP sessions you can have is 
subjective, and depends a lot on the environment.

I would imagine having more than 90 BGP session if you were 
receiving no more than a couple of routes from each of the 
peers.

At my previous employer, we once had a C box that carried 99 
sessions, most were a couple of hundred to a few thousand 
routes, with two or three carrying full feeds - and this 
was with a processor that I can say is not as powerful as 
the Intel ones running on the J-series today, both being 
software platforms and all.

The M7i would still handle BGP in software, since that's a 
control plane feature.

So it comes down to how many routes you'll be receiving from 
each of your peers, how optimized your BGP configuration 
will be, how late the code you'll be running is and how 
(un)stable those peers are likely to get.

Cheers,

Mark.
