Hi,
In general, how is a BGP implementation evaluated/benchmarked by an
operator?
Are there any well-known figures relating to memory-consumption, speed of
convergence, scalability etc. that one can benchmark with?
There was a write-up on Data Comm magazine testing Juniper's M40 BGP. I
haven't seen much more than that - especially test procedures used to
compare various vendor implementations.
Thanks in advance,

Some standardization work for BGP convergence is
going on BMWG of IETF.

They consider only single device convergence and
mostly external measurements. I have found the route
flap test useful.
It also has a companion terminology document.

If you are more particular on performance in the
forwarding plane, consider RFC 2544. I have not gone
through the RFC
though(http://ietf.org/rfc/rfc2544.txt).
