The Dynamic Host Configuration Protocol (DHCP) is an Internet Engineering Task Force (IETF) standard protocol designed to provide a framework for passing configuration information to hosts on a TCP/IP network. For an introduction to the DHCP Protocol, see [RFC2131] section 1.
DHCP allows for multiple servers to be operating on a single network. For such servers to provide redundancy in case of server failure, the cooperating servers have to maintain a consistent database of lease information. The DHCP Failover Protocol [IETF-DHCPFOP-12] defines a way to synchronize the lease information between two DHCP servers.
This document specifies a set of extensions to the DHCP Failover Protocol.
Sections 1.5, 1.8, 1.9, 2, and 3 of this specification are normative. All other sections and examples in this specification are informative.
