bogus route announcements on IETF wireless LAN

[Simon Leinen <simon@limmat.switch.ch>]

For some of us, IPv6 isn't really usable here at the IETF meeting,
because there are so many bogus route announcements.  At the moment, I
see four 6to4 prefixes (two of them with RFC1918 base addresses, no
idea where those come from), one site-local prefix, and two prefixes
from the IETF meeting range - no idea which of these would work.

If my host implemented RFC 3484, I could probably deprecate all these
prefixes, but unfortunately it doesn't.  So I have to disable
stateless address autoconfiguration (which is a pain) or use IPv4 :-(

So PLEASE turn off IPv6 router advertisements on your laptops.

Thanks!
