This is mostly correct, To properly implement BGP, you should have your own AS #. Alternately, If you can't ante the $5000 to get the #, then you may be able to talk the ISP's into letting you use a private As number that they strip off and replace with their AS#.
I.e. Internet - Isp1 (701) - You (65530) - Isp2 (16770) - internet A looking glass on the internet would see (assuming you are 1.1.1.0/24) Subnet ---------- AS Path 1.1.1.0/24 ---- 701 1.1.1.0/24 ---- 16770 A looking glass inside UUnet (701) would see (assuming you are 1.1.1.0/24) Subnet ---------- AS Path 1.1.1.0/24 ---- 701 65530 1.1.1.0/24 ---- 16770 A looking glass inside Broadslate (16770) would see (assuming you are 1.1.1.0/24) Subnet ---------- AS Path 1.1.1.0/24 ---- 701 1.1.1.0/24 ---- 16770 65530 They would have to do a wee bit of engineering on there part to make their routers prefer the longer AS path, but technically it is doable. -ejay Btw, I've never agressively looked, but I don't know of any Isp's that will let you do this. If anyone needs assistance with BGP configuration, e-mail me off list.

If I don't have my own AS number, I can not connect to two ISPs? Please help, thanks.
