RE: new version of the CPE Rtr draft is ready for review

Janos,

Using SLAAC/ND proxy on the uplink can give some security implication
for sure when N:1 broadband architectures are used, so I think it is
better to use DHCP/DHCP PD to overcome these. service providers are used
to DHCP in broadband environments.

My 2 cents.

Cheers,
Wim

I think NDproxy is one option - option for clueless users how just
connect their devices directly on the CPE wired/or wireless and not
configuring any VLANs or subnets.

I think more than95% percent of the home users belongs to this category.

More sophisticated methods (DHCPv6 with prefix delegation) could be
offered to the rest of the users...

I think ND proxy could be used for mass IPv6 broadband deployment:
- no configuration required from end users on their router box if
NDproxy is supported and switched on by default.
