Fred,

I had reviewed draft-ietf-v6ops-reducing-ra-energy-consumption-00 and 
fully agreed with the the recommendations in section 4 about 
implementation and configuration of routers.

However, in 01 there was a section added (4.2 - now 5.2) with device 
side recommendations/requirements, with with I have serious reservations 
at several levels:
1. The text uses terms like "maintain IPv6 connectivity" and "disconnect 
from the IPv6 network" which are not defined. I would not know what 
impact this has on an implementation with those terms being defined. 
E.g., does "disconnect" mean to discard all IPv6 addresses and prefixes 
and release all DHCPv6 leases? Kill all connections? What?

2. Section 5.2 changes (or at least clarifies) the IPv6 standards which 
seems to not be in scope in the v6ops charter.

Thus I think section 5.2 should be removed and that discussion be had in 
the 6man WG.

Sorry for not catching the scope expansion in -01 earlier.

Regards,
     Erik
