FYI, there is an interesting document entitled:

   "Multi-link Subnet Support in IPv6"
   http://www.ietf.org/internet-drafts/draft-ietf-ipv6-multilink-subnets-00.txt

that speaks to nodes with multiple links connecting to a single network.

P.S. The above document is a somewhat controversial wg item of the
      IPv6 wg; this message should be seen as informational-only and
      not an endorsement.
