That is correct.  CableLabs has defined the standards for the IPv6 Cable
Router in their network with no mention of the IsRouter flag.

flag. There will be no NS

Hmm, why won't a SP Rtr send an NS to the CE Rtr?  For one, the SP Rtr
can send an NS to resolve the link-local or global of the WAN interface
of the CE Rtr.

>So there will be no solicited NA or RA messages coming from the CE
routers. 

The CE Rtr can send an NA in response to the NS I mentioned above.
