DHCPv6 failover protocol?

While poring over RFC3315, I was curious how the validation section for Renew
and Rebind messages interacts with failover. The RFC states that for Renew
messages:
Servers MUST discard any received Renew message that meets any of the
following conditions:
- the message does not include a Server Identifier option.
- the contents of the Server Identifier option does not match the
server's identifier.
So if you have two servers, A and B, and server A goes down, how will server B
react? Is it permitted to start answering messages with the DUID of A, or
does it have to wait for the clients to give up and send out a new Solicit
message?
