This document specifies protocol enhancements that allow transparent
routing of IP datagrams to mobile nodes in the Internet. Each
mobile node is always identified by its home address, regardless of
its current point of attachment to the Internet. While situated
away from its home, a mobile node is also associated with a
care-of address, which provides information about its current
point of attachment to the Internet. The protocol provides for
registering the care-of address with a home agent. The home agent
sends datagrams destined for the mobile node through a tunnel to
the care-of address. After arriving at the end of the tunnel, each
datagram is then delivered to the mobile node.

This document specifies a method by which an IP datagram may
be encapsulated (carried as payload) within an IP datagram.
Encapsulation is suggested as a means to alter the normal IP routing
for datagrams, by delivering them to an intermediate destination
which would not be otherwise selected by the (network part of the)
IP destination field. This may be done for any of a variety of
reasons, but is particular useful for adherence to the mobile-IP
specification.

This document specifies a method by which an IP datagram may
be encapsulated (carried as payload) within an IP datagram,
without incurring all the overhead of using a standard IP header.
Encapsulation is suggested as a means to effect ``re-addressing"
datagrams (i.e, delivering them to an intermediate destination other
than that specified in the IP destination field) for any of a variety
of reasons, but particularly those useful for adherence to the
mobile-IP specification.

This document defines extensions to the operation of the base
Mobile IP protocol to allow for optimization of datagram routing from
a correspondent node to a mobile node. Without Route Optimization,
all datagrams destined to a mobile node are routed through that
mobile node's home agent, which then tunnels each datagram to the
mobile node's current location. The protocol extensions described
here provide a means for correspondent nodes that implement them
to cache the binding of a mobile node and to then tunnel their own
datagrams for the mobile node directly to that location, bypassing
the possibly lengthy route for each datagram to and from the mobile
node's home agent. Extensions are also provided to allow datagrams
in flight when a mobile node moves, and datagrams sent based on an
out-of-date cached binding, to be forwarded directly to the mobile
node's new binding.

As required by [RFC 1264], this draft report discusses the
applicability of Mobile IP to provide host mobility in the Internet.
The final form of this draft report is a prerequisite to advancing
Mobile IP on the standards track. In particular, this document
describes the key features of Mobile IP and shows how the
requirements for advancement to Proposed Standard RFC have been
satisfied.

This document specifies mobility messages that allow transparent
routing of IP datagrams to mobile nodes in the Internet. Each
mobile node is always identified by its home address, regardless of
its current point of attachment to the Internet. While situated
away from its home, a mobile node is also associated with a
care-of address, which provides information about its current
point of attachment to the Internet. The protocol provides for
notifying the mobile node's home agent, and any other interested IPv6
addressable entities, about the care-of address of the mobile node.
When necessary, the home agent sends packets destined for the mobile
node through a tunnel to the care-of address. After arriving at the
end of the tunnel, the packets are then delivered to the mobile node.

This memo defines the Management Information Base (MIB) for use with
network management protocols in TCP/IP-based internets. In
particular, it describes managed objects used for managing the Mobile
Node, Foreign Agent and Home Agent of the Mobile IP Protocol.
