You don’t think that AT&T the DSL SP will know what AT&T
wireless might be doing with a device that’s connected to AT&T the application
service provider? J Oh ye of little faith. Have you never seen the movie “The
President’s Analyst”? But no, in the case you describe, the cellular network that provides
this iPhone with 3G connectivity would need to send route info in its RA, specifying
the prefixes of its walled garden, to the iPhone. If the DSL connection is just
a plain vanilla connection, there would be no route info coming at the iPhone
from its Wi-Fi interface. The DSL provider doesn’t need to know about the 3G
connection – only the iPhone knows. Barbara From: Hemant Singh
(shemant) [mailto:shemant@cisco.com] Barbara, You are also asking for the impossible. As a cable
or DSL SP, you don’t know what the IPv6 prefix my IPhone from AT&T is using
for the cellular network? So how can any MSR be devised and propagated
from the SP router serving the broadband modem in the home to send an MSR for a
prefix not known to them? Our new text is fine. Hemant From: Stark, Barbara
[mailto:bs7652@att.com] It's not clear
to me why manual configuration is specified as *the* way to configure these
routes (again, I see RA (RFC 4191) from the access network to the CPE Rtr WAN
interface as a way to configure the routes). I propose that if a CPE Rtr gets
such routes from the WAN that it automatically put those same route prefixes in
its LAN RAs. In which case it would not be off by default, but on by default (it
would automatically send specific route info if it has specific route info to
send). ***** The
