RE: IPv6 on SOHO routers?

Besides the CM and CMTS itself, can the CPE attached to the CM use IPv6 if
the CMTS has the right code to handle IPv6-based DHCP relay?  To be clear,
even if the CMTS doesn't have DOCSIS 3.0 support?  Standing from a distance,
I don't see why IPv6 on the routing piece of the CMTS has to require a
DOCSIS 3.0 blade and/or CM.

Any cablelebs certified docsis 3.0 CM or CMTS supports ipv6.

Your cable provider will have to upgrade their CMTS (line card swap)
before you can leverage it directly on the cable in a consumer environment.

DSL aggregation routers are challenge where again equipment lifecycle
plays in to whether you're in a position to deploy.
