This is a list of three questions. Until there is discussion of the first, it is premature to address the second two. Therefore, how about we just choose a specific case of the first: how would BGPSec protect against an instance of an event found here: http://puck.nether.net/bgp/leakinfo.cgi > you are correct, BGPsec tries to secure the BGP protocol against abuse, > not protect the internet. the latter is a very worthy goal but a bit > nebulous. of course an internet draft or two might clarify that. This seems like a very pedantic distinction. Having an AS' traffic routed through an invalid path seems like a BGP protocol abuse to me. So, in that language, it seems to me that this issue is in scope (i.e. if the path is to be protected, then subverting it is an abuse).
