That is a possible scenario. If they are willing to tie the static route to their interface toward your net, that static route would be dynamically removed. Also, technologies like cisco's ip-sla would get you part of the way there. If they won't run bgp with you, one of the static route options is probably your only reasonable hope. All of the above are inferior to bgp. The best advice that I've heard thusfar is to deal with this the best way possible, and then start shopping. ----- Original Message ----- From: Charles Regan <charles.regan@gmail.com> To: nanog@nanog.org <nanog@nanog.org> Sent: Fri Feb 06 12:08:53 2009 Subject: Re: One /22 Two ISP no BGP Quick questions.

I want to advertise my /22 to two different ISP on different POP.

I can't use BGP as ISP1 doesn't support it.

Any suggestions ?

Thanks, Charles
