Manual configuration that may be required to be updated by
the Service Provider may be exposed through SNMP in the CPE
Router.
Therefore, we could provide a way to insert routes into the
MSR table through SNMP queries.
However, other routes may need to be configured by the
end-user, so the MSR table may need to be exposed to the end user as
well.

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

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
