The IETF has not finished the v6 failover protocol draft.  It is currently
being worked on in the DHCP working group.  See 
https://datatracker.ietf.org/wg/dhc/documents/
for information about the WG and
https://datatracker.ietf.org/doc/draft-ietf-dhc-dhcpv6-failover-protocol/
for the protocol itself.

As v6 has a much larger address space you may also be
able to avoid using a failover set up by simply running multiple
DHCPv6 servers with non-overlapping address pools.  This
will provide redundant DHCPv6 service but will require that
client get new addresses if the server they originally got an
address from becomes unavailable.

Shawn
