Randy. You are not 100% right. Often the XX's customer is forced to use another ISP for internet access (for example, customer change location and could not order digital trunk from the new one), but can't renumbered quickly. And so on... You can anounce specifics of the other ISP, and it allow this customer to work for some time and be successed. Through, some cases (if you lost external connectivity, for example, but you have peering connectivity with XX, for example) cause you to use bandwidth of XX, or XX can be acused in waisting routing-table-space, or the prefix-length limitations (by such ISP as Sprint) cause some mirrouting, etc etc... THis means we always treat such decisions as _temporary_ and always ask permission fro the net-block owner to do it; and vice versa. Alex. ---- On Wed, 24 Mar 1999, Randy Bush wrote:

do you require any documentation from their other provider that they are allowed to re-announce those addresses? The issue isn't whether we should re-announce, but what documentation we should require before doing so.
uh, we're kinda on a first name basis with our peers at the other tier ones. formality is usually not needed.
when one of their less clued/connected departments gets involved, we usually count on the clueful to handle their own organization's internal issues.
most folk really do understand how the game is played. probably verio stresses it more than most, due to much address space still swipped into the name of the isps we acquired and there is major administrivia (legal sale documents and all) to update it. but most of our friends know that too. occasionally we hit an peer's admin person who's been kept in a dark room for some years. again we could on the clueful to pass it on.
