[ Moderator note: changed local-ir@ripe.net -> ipv6-wg@ripe.net ] Could somebody take the time to explain how multi-homing works in this setup ? I have either not grasped it or not found the place where it is described. Lets take a small ISP who have "upstream" connections to one TLA and two sub-TLA entities. Are they required to become a sub-TLA ? if yes: What if they don't meet one of the formal requirements for that ? Would failing to become a sub-TLA prevent them from opening "general" peerings with one or more of these (sub-)TLAs ? (in other words: will these policies discourage and prevent multihoming ?) if no: Which IPv6 numbers will they use ? How will route-aggregation work in this case ? Will each host have 3 IPv6 numbers listed in DNS ? Sorry if these are stupid questions, but I'm probably not the only one being unenlightened in this area... -- Poul-Henning Kamp FreeBSD coreteam member phk@FreeBSD.ORG "Real hackers run -current on their laptop."
