Consider a scenario where a home has 2 routers, each connected
to a different access network (maybe one is cable and the other DSL). Each SP,
in addition to providing Internet access, also provides access to a walled
garden of special services accessible only by their subscribers. This walled
garden uses an address space not accessible from the Internet. This walled
garden might require the CPE router to set up a separate WAN connection, or it
might not. Wouldn’t the access networks , in this case, need to tell
the CPE routers connected to them that this address space is accessible off
this network? And wouldn’t the CPE Routers need to tell the hosts in the
LAN which of these walled garden address spaces gets routed through each of
them, so hosts know where to send traffic bound for a server off one or the
other of these private networks? I’ve seen these things rather often in IPv4, where the CPE
Router is statically configured (by the SP) to know what to do. But if the address
space needs to change, updating the configuration is clumsy. It seems that the
tools available to us with IPv6 could allow us to do better. Barbara From: Alan Kavanagh
[mailto:alan.kavanagh@ericsson.com] Hmm, im a little bit confused here or just missing some of this
discussion, but what "routes" are you considering being advertised by
the BNG/IP_Edge node and what routes would be then advertised from the WAN to
the Home LAN network? Alan K From: owner-v6ops@ops.ietf.org
[mailto:owner-v6ops@ops.ietf.org] On Behalf Of Stark, Barbara 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
