RE: New (-02) version of IPv6 CPE Router draft is available for review

["Hemant Singh (shemant)" <shemant@cisco.com>]

Even in a cascade there is only one CPE Router that directly faces the
SP upstream router.  This is the router that will proxy MLD reports to
the SP.  This will work if the first CPE Router in the cascade (facing
the SP) is configured for lowest IP address (section 3 of RFC4605).

We are working on changing our mcast section in the draft to reference
RFC4605 since Remi pointed to us we were re-inventing MLD proxy when an
RFC existed on the subject.  We need to work out the details for mcast
in the cascade and propose a smallest common denominator for mcast in
the cascade.

The -02 draft states:

'Querier Election rules as described in section 7.6.2 of [RFC3810] do
    not apply to the CPE Router since the home network has only one
    router.  Therefore, the CPE Router must always act as an MLD querier
    on its LAN interface(s).'

This is not a good assumption considering there's already been
discussion of cascading these routers.
