Is it permissible, from a policy perspective, for a multi-homed end user to announce the numbering resource allocation received from one RIR (for discussion purposes, let's say ARIN) to upstream service providers in a different region (for example, in the RIPE region)?
Nope. The RIR-police will shut you down.
Mean, Jon. Mean. 8-)
Just kidding. I'm in ARIN's region and have a customer in Africa for whom we're announcing AFRINIC space. It happens. As long as you have authorization from the registrant (I'd say owner, but the RIR-semantics police would come for me) of the space, I wouldn't worry about utilizing "out of region" numbering resources.
This sort of thing probably happens quite a bit more than you'd guess...both legitmately and not.
I believe all the big multihomed multinational organizations generally all do this; the ones I've worked with (banks) all did. It would sort of defeat the purpose of multihoming if you couldn't announce not just to other providers, but in some circumstances multi-geographically. If my multihoming crosses a RIR boundary it's still multihoming. One of those RIRs is probably "home territory" to ask for allocations from, but in any case there shouldn't be a technical or policy block to anouncing ARIN space in RIPE land, or any similar variation thereof. -- -george william herbert george.herbert@gmail.com
