Hi Ron,
Kind Regards, Adeel Ahmed.
Perhaps a scenario not captured in this draft (unless I missed it) that would be good to capture in the cable BB section is IPv6 enabled on the CM, CMTS, ER for management purposes. Portions of the cable infrastructure have traditionally used RFC1918 IPv4 addresses; however, there are a finite number of those. Thus, IPv6 could have utility in the cable space implemented on the control plane initially rather than focused on the data plane for end user services. Nice draft!
