so, say you end up with a /24 and your ASN split up your /24 into hq-/25 and colo-/25 from colo: 1) announce /24 as a standard adv 2) announce colo-/25 with *no-export* community set from hq: 1) announce /24 as a standard adv 2) announce hq-/25 with *no-export* community set Run iBGP over a dedicated link b/w colo and hq (I don't like allow-as in! but it is another option) ./Randy --- On Thu, 6/14/12, Philip Lavine <source_route () yahoo com> wrote:

Hard part: I also need to provide incoming access to hosted apps (HTTP, FTP, SMTP) from either location, so if the colo internet connection goes down the traffic can re-route to the HQ server farm and visa versa. I am in the process of purchasing an AS and ip space. Is it advisable to use the same IP space at both locations and run iBGP over a dedicated L2 connection between the sites.
