Current specifications of Mobile IPv6 does not provide Home Agent
Reliability in the home link. The aim of this draft is to introduce
Virtual Home Agent Reliability Protocol as the solution. In this
protocol multiple Home Agents coexist on the same home link and share
the same Global IP address. Only one of them is active at a time and
serves the Mobile Node. The Home Agent failure and failover
mechanisms are completely transparent to the Mobile Node which is
required for minimal service interruption time. This protocol does
not introduce any new Mobile IPv6 message over the air interface and
thus helps reducing the overall overhead. Current specifications of Mobile IPv6 does not provide 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
