Title : Securing Home Agent List in MIP6
Author(s) : S. Dutta, et al.
Filename : draft-dutta-mip6-ra-00.txt
Pages : 7
Date : 2005-7-8
This document identifies one type of the denial of service attack
which can be possible in Mobile IP6 and tries to propose a solution
for same.
Currently in MIP6 each Home Agent is required to maintain a home
agent list. This home agent list is generated by receiving RA
messages on the home link and the addresses learned are sent to
Mobile node when it does Home Agent discovery. On learning this list
MN tries to register with addresses in this list one by one in order
of preference. Now if the home network is flooded with spurious RA
packets having high preference value the home agent list is populated
with non reachable addresses and no mobile node is able to register
from that home network
This document proposes to first carry out reachability confirmation
for each home agent entry before adding to Home Agent list

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
Internet-Draft.
