This document describes an inter Home Agents (HAHA) protocol to provide multiple Home Agents support for both Mobile IPv6 and the Nemo Basic Support protocol.  The HAHA protocol provides Home Agent redundancy and load-balancing for both protocols.  The HAHA protocol allows multiple Home Agents to be placed at different links.  It also allows a Mobile Node/Router to utilize multiple Home Agents simultaneously.  The protocol consists of 3 mechanisms, Home Agent List management, Binding Synchronization, and Home Agent Switching. A Mobile Node/Router picks one Home Agent as its primary Home Agent and registers with it.  The primary Home Agent synchronizes the binding cache information with
other Home Agents.  Any of Home Agents can intercept a packet meant for the Mobile Node/Router and tunnel the packet directly to its current Care-of address.  Alternatively, the Home Agent can tunnel the packet
to the primary Home Agent.

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.
