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 new text for MSR's is as
follows:
"8.7 Multi-homed Host Support (MEDIUM)
The CPE Router MAY
support RFC4191 on its LAN interfaces. Small
consumer embedded
multi-homed hosts in the home may not have
configurable routing tables.
The CPE Router can communicate More
Specific Routes (MSRs) to these hosts to
allow them to choose a
preferred router to send traffic to for traffic
destined to specific
prefixes configured through manual configuration.
Advertisement of MSRs
through RAs is turned off by default."

I take it back. It's interesting in the other cases as
well. Two CPE
routers attached to the same link will exchange their
prefixes with MSR
advertisements regardless of whether the RAs from the
service provider
have PIO options in them. As they
should.
