RE: WLAN (was Re: IPv6 Host Configuration of Recursive DNS Server)

["Pascal Thubert \(pthubert\)" <pthubert at cisco.com>]

Interestingly, part of this pain comes from the decision to provide
Ethernet emulation for 802.11, while some practical use cases do not
actually require a broadcast medium.

In particular, in the case of public access points, the desired effect
is a point to point connectivity with the access point; seems that a PPP
support over the Wireless MAC layer would have done the trick perfectly.
For MIPv6, though, there's also the pain that IPv6CP would not provide
an IPv6 address to the mobile device anyway.

But all this can be worked out :)
