Re: Comments on draft-jinmei-ipv6-rfc2462bis-00.txt

[Thomas Narten <narten@us.ibm.com>]

One more point:

One of the original motivations for disabling an interface if DAD
fails for the LL address is that if you are running DAD on a LL
address generated using the EUI-64 format, in the absence of a DOS
attack, if DAD fails, that really means duplicate ethernet addresses
are in use. In this case, the device is hosed and configuring another
address won't result in a usable network. In fact, it probably makes
things worse by creating problems that harder to diagnose than just
shutting down the interface. The user will see a partially working
network where some things work, and other things won't.

BTW, some of the above text might be worth putting into 2462bis as
background information.
