Hi Menachem,

I would add reference. It's defined in section 5.4 of the MPL draft.

Is this clear?: "other method to protect integrity between DHCPv6 
servers and clients"
My intention is the next sentence on ZigBee IP is an example.

I mean remote DHCPv6 server case.

Is this clear?: "DHCPv6 packets SHOULD be filtered on the border router 
between the ROLL network and the Internet, except for the packets 
between the ROLL network and a remote DHCPv6 server or DHCPv6 relays 
configured to manage the network"

Thanks, I would update and clarify the sentences on your review on the 
next revision.
