The DHCPv6 protocol, defined in RFC 3315, allows for multiple servers
to operate on a single network; however, it does not define any way
the servers could share information about currently active clients
and their leases.  Some sites are interested in running multiple
servers in such a way as to provide increased availability in case of
server failure.  In order for this to work reliably, the cooperating
primary and secondary servers must maintain a consistent database of
the lease information.  RFC 3315 allows for, but does not define, any
redundancy or failover mechanisms.  This document outlines
requirements for DHCPv6 failover, enumerates related problems, and
discusses the proposed scope of work to be conducted.  This document
does not define a DHCPv6 failover protocol.

This document is a product of the Dynamic Host Configuration Working Group of the IETF.
