About the BGP peering sessions.

Hi,

I am a new member on this list.

I had a question regarding the nature of the BGP peering sessions of
the RRCs. Is there any place I can find accurate information about the
way the different RRCs maintain their peering sessions; as in how many
of the sessions are multi-hop BGP sessions and how many are direct
link sessions etc?
I was wondering about this since, there has been a paper (see below)
published in 2002 that said that most of the RRCs peering sessions
were multi-hop eBGP sessions and as a result the BGP data collected
here cannnot be an accurate refelction of what goes on the actual
Internet/backbone routers.

"Observation and Analysis of BGP Behavior under Stress", Proceedings
of the Second ACM
SIGCOMM Internet Measurement Workshop (IMW '02), pp. 183-195, Nov. 2002

Any inputs that I can get regarding this will be very helpful.

Shivani.
