	Title		: DHCP Failover Protocol

DHCP [RFC 2131] allows for multiple servers to be operating on a
single network.  Some sites are interested in running multiple
servers in such a way so as to provide redundancy 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.  This implies that servers will need to coordinate
any and all lease activity so that this information is synchronized
in case of failover.
This document defines a protocol to provide such synchronization
between two servers.  One server is designated the 'primary' server,
the other is the 'secondary' server.  This document also describes a
way to integrate the failover protocol with the DHCP load balancing
This document is a substantial reorganization as well as a technical
and editorial revision of draft-ietf-dhc-failover-05.txt.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

implementation to automatically retrieve the ASCII version of the
