(1) RFC2461 appendix A is too vague to implement something workable,
and (2) RFC2462 does not give any provision on how one should behave
on multiple RAs from multiple interfaces, for example, routing
table setups (default router list).

Agreed, my words were too restrictive. Sorry about that. As seen in
separate message, (1) there's no spec (2) kame code follows RFC2462
for autoconfiguration, which talks only about autoconfiguring hosts
(not routers). I'll update manpages if there are any wording like this.
