How did you get a /22, and what isp won't run bgp with you? ----- Original Message ----- From: Charles Regan <charles.regan@gmail.com> To: nanog@nanog.org <nanog@nanog.org> Sent: Fri Feb 06 11:29:28 2009 Subject: One /22 Two ISP no BGP 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
The ISP may not support peering BGP with you, but can they publish routes for you? I find it hard to believe ANY ISP just "doesn't support BGP". On Fri, Feb 6, 2009 at 10:32 AM, Michael Smith <msmith@internap.com> wrote:

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

It is very possible that the ISP doesn't support BGP, but more likely, I'd bet that the ISP has never configured BGP on the client end of their network, and aren't too anxious to figure out how to do so. Steve
Pick your preferred link in, have them announce your /22, have the other provider announce the /22, just weighed. That way you are multi-homed with failover. After that is configured, find a new ISP to replace the one that will not let you peer with them. Jason On Fri, Feb 6, 2009 at 10:52 AM, Steve Bertrand <steve@ibctech.ca> wrote:
