Do I need global IPv6 addresses on the link? It's not required, so if you don't actually need it for anything then just don't bother allocating any.
That's a good question, which remains to be answered... ;-) Amongst other things, a few in-band management issues have to be resolved. Might need some sort of at least internally routable address on the external-facing interface for a while. Luckily with v6 comes the freedom of multiple approaches...
Should the prefix I assign to the customer's LAN (presumably by DHCPv6-PD) be dynamically allocated? People have different opinions here. There isn't a right or wrong answer. But the question should be asked, since the number of available addresses means that you *can* allocate a static prefix for every end user site.
Definitely. As v6 support is getting noticably better (bugs are squashed and different brands of equipment are starting to agree on how to speak to each other), I'm leaning towards making end-user prefixes as static as possible. Up until not too long ago, some of our equipment even refused to re-assign the same prefix ("error: already assigned"). One bug down... ;-)
Personally I hate renumbering, and can't understand why I should force that on innocent users :-)
I completely agree. -- Vegard Svanberg <vegard@svanberg.no> [*Takapa@IRC (EFnet)]
