Devil's advocate: if you have links to two carriers, but they are delivered via the same LEC on the same fiber, are you multihomed? What about if you have two LECs at your facility, but the two circuits share a common path elsewhere (outside of your knowledge)?
I'd say you are. End users frequently don't know the layout of their carrier's networks, and I certainly wouldn't expect ARIN to be interested in that level of detail. What's next? Are you going to ask if I'd require that your router have dual power supplies from different UPS's, or that if they don't have dual power, you have a router per transit connection? It's a shame ARIN's auditors don't hang out here (or if they do, that they don't jump in and end these sorts of "what if" circle-jerks). It's a simple enough question...have they already seen applications for IP/ASN resources where the applicant was required to be multihomed and their connectivity was one leased line and a GRE tunnel with BGP to a second provider. Was the request approved? How many providers will even provision such a service? ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
