FYI,
IPv6 Neighbor Discovery installs default routes on every interface with a
high metric, i.e., if no other way to know how to treat the packet, it's
assumed to be "on-link".
This causes a number of problems, especially if you have enabled IPv6 but
don't have IPv6 connectivity yet.
This "feature" will likely be removed from Neighbor Discovery in its
revision.
Just to give a heads-up before this is finalized, to give people ability
to prepare or comment prior to this process is formalized in the IETF.

A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the IPv6 Operations Working Group of the IETF.
Title : IPv6 Neighbor Discovery On-Link Assumption
Considered Harmful
Author(s) : S. Roy, et. al.
Filename : draft-ietf-v6ops-onlinkassumption-00.txt
Pages : 11
Date : 2003-10-22
This document proposes a change to the IPv6 Neighbor Discovery
conceptual host sending algorithm. According to the algorithm, when
a host's default router list is empty, the host assumes that all
destinations are on-link. This document describes how making this
assumption causes problems, and describes how these problems outweigh
the benefits of this part of the conceptual sending algorithm.

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.
