No recollection of this. Did I respond? I'm trawling my list archive
because I *know* someone sent me a patch to fix the Juniper multiple
DNS search domain issue.

I'd take a look at IPv6 Prefix Delegation as handled in PPP and DHCPv6.
It hands out subnets to the client and the client can then run RA on
its *other* interfaces (and hand them out further, perhaps).

I think it's normally done as a *separate* configuration item to the
main IPv6 address. Yes, there are plenty but there's no reason to be
entirely profligate with them. You can have a /127 for the point-to
-point link, and multiple /64s for the subnets you want to route to.
