DHCPv6 Failover Requirements

Metadata

Publisher: IETF
Doc Type: Informational
Pages: 17
Abstract: 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.
