Re: Response to Dave Thaler regarding server-initiated DHCPv6

[Suresh Krishnan <suresh.krishnan at ericsson.com>]

Hi Ralph,
  I was just commenting that the addressing policy changes triggered by 
routing changes are best initiated by the router and all the other 
policy changes are best initiated by the DHCP server. I was not 
commenting on the suitability/ease of use of the delivery mechanism(s) 
at all.

Thanks
Suresh
