During some IPv6 numbering discussions at work today, someone had a question that I hadn't really considered before. How to choose 32-bit router IDs for IPv6-only routers.
Why would you do it differently than for dual-stack routers, except that you skip the step where you configure the ID as a loopback address? Of course you don't have care about routing the 32bit IDs anymore either. But that doesn't really change anything either. Except that can skip even more configuration. It's obviously possible to connect the ID to some IPv6 address on the router, as long as you understand the structure of that allocation and can select the right bits or hash to make it unique. But if you don't do that for dual-stack today, then why care? Or if you do it for dual-stack, then what changed? Bjørn
