There is an other way, strange but working - don't use ASn at all, use the ASN of the providers with some IGP or _bgp over private AS_ protocol. It work. (I do not advise this, btw). On Thu, 9 Dec 1999, Randy Bush wrote:

First, it's my understanding that I can use a single ASN for the BGP peering at each of these networks. Am I mistaken? if you don't care to reach one from the other. Well, you _can_, if you want to put the time and effort into performing the evil routing voodoo. I can think of a few ways of doing it, without even bridging over a tunnel. I wouldn't advise it, however.
i disagree strongly. i think it is a really great idea for our competitors to deploy.
