The advisories I have seen have made this same statement. However, according
to another list I read there are a number of network operators who feel this
is not a real threat. A number of them hold that it would be excessively
challenging to be able to match up the source-ip:source-port and
dest-ip:dest-port and effectively reset a BGP session without generating a
large volume of traffic, which should be noticed in and of itself. So, I am
wondering what people have been seeing, anyone yet seen evidence of an
attempt to exploit this?

Well - in that case, you'd be depending on how truely random the
source_ip:source_port and dest_ip:dest_port combinations are.  We already
know that three of these pieces of information aren't hard to obtain.

cheers!
