The curious thing here is that the peer that resets the session, as
required by the spec, causes the actual damage (the session reset),
and not the peer producing the wrong update.
This whole thread is quite schizophrenic because the consensus appears
to be that (a) a *researcher is not to blame* for sending out a BGP
message which eventually leads to session resets, and (b) an
*implementor is to blame* for sending out a BGP messages which
eventually leads to session resets. You really can't have it both
I'm fed up with this situation, and we will fix it this time. My take
is that if you reset the session, you're part of the problem, and
consequently deserve part of the blame. So if you receive a
properly-framed BGP update message you cannot parse, you should just
log it, but not take down the session.
