I've found that this setup, in conjunction with iBGP peering between
loopback /128's works well.
When OSPFv3 goes down and you are trying to debug, what IPv6 will you
ping to check if the second side is accessible?
FWIW, I like to use static, meaningfully-assigned Link Locals ... regardless
of the link type.
