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. 

regards, 
Shawn
