We've a 6509, SUP2, MSFC2, in hybrid, known as switch8.oct and msfc1.oct
(same physical box):

There are about 20 peers on this, three of which are full views.

seperately, we have a 6509, sup1, msfc2, in integrated:

msfc1.nyc>sho mem
                Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)

(how do you check free SUP ram on an integrated box?)

msfc1.nyc#sho ip bgp sum
BGP router identifier 209.123.12.4, local AS number 8001
BGP table version is 17174893, main routing table version 17174893

BGP activity 300078/110778093 prefixes, 14305643/13981791 paths, scan interval 15 secs

This box has about 50 to 70 peers, two are full views, seven or so are
internal mesh, and the rest range from 0 to several thousand.

If you want, http://eng.nac.net/lookingglass/ has ways for you to access
both of these boxes if you please.

Hope this helps.
