If this is true, then why do the european NAP mailing lists (which push
IRR filtering) have an almost constant stream of "oops, our customer
announced everything to us and we leaked it".
Because European naps have more smaller and clueless players. I
know more than a few people (because they ask for peering) who have
an IRR entry that is 1 prefix for the "ISP", and 1 prefix for their
only BGP customer. It should be of no surprise they get that
customer configured wrong. It should also be of no surprise that
most of the real ISP's would never consider peering with those types
CAIS (or whatever they're called today - BtNAccess/PCCW) is a small and
clueless player? Then why is 6461 peering with 3491?
(yeah, that was a customer route leak in July. I tend to just delete such
emails, but I'd be surprised if there weren't more in August from ISPs that
don't fit into "small and clueless")
Not everyone filters their customers, and saying that everyone that counts
does doesn't make it so.
6461 filters all customers by prefix list. Note too, filtering
customers does not eliminate route leaks, it just removes the most
obvious and often cause.
Really? So how was I able to advertise a new netblock to one of your
customers just now and see 6461 <their AS> <my AS> on
route-views.oregon-ix.net within 2 minutes and without telling a soul what
I was doing? You must have some pretty broad prefix lists. (And no, it
doesn't make me happy that I was able to do this... there are 2 places that
are missing filters in that path).
At least I *think* that they are your customer, if not, then you're leaking
routes to Sprint and opentransit and telia amongst other places.
