Abstract

This document defines a DHCPv6 failover protocol, which is a mechanism for running two DHCPv6 servers [RFC3315] with the capability for either server to take over clients' leases in case of server failover or network partition. For a general overview of DHCPv6 failover problems, use cases, benefits, and shortcomings, see [RFC7031].

                         DHCPv6 Failover Protocol

Abstract

   DHCPv6 as defined in "Dynamic Host Configuration Protocol for IPv6    (DHCPv6)" (RFC 3315) does not offer server redundancy.  This document    defines a protocol implementation to provide DHCPv6 failover, a    mechanism for running two servers with the capability for either    server to take over clients' leases in case of server failure or    network partition.  It meets the requirements for DHCPv6 failover    detailed in "DHCPv6 Failover Requirements" (RFC 7031).
