Actually, that was "a", what I call prefix theft. I figure it is becoming more and more common, and I know of at least one case where it was an actual policy of a large network.
I don't see how it can be on the rise. When FDT multihomed, we had to arrange with both our providers to accept our route. Why aren't all the big providers putting distribute lists on their customer BGP peers? The access-lists should change infrequently enough that it wouldn't be a big deal to maintain, and it would make the net a better place. If I totaly hose our BGP setup and announce crap to either provider, nobody will be affected. In fact, I think I did this the first night I setup BGP. Nothing bad happened. While they're at it, they could use the same data to setup/maintain ingress filters. Last I heard, Cisco had finally made it so that non-logged extended access-list filtered packets are still fast switched. ------------------------------------------------------------------ Jon Lewis <jlewis@fdt.net> | Spammers will be winnuked or Network Administrator | drawn and quartered...whichever Florida Digital Turnpike | is more convenient. ______http://inorganic5.fdt.net/~jlewis/pgp for PGP public key____
