Hi Erik,

Thanks for the comment.

There is probably no difference: the CPE connects its LTE interface to
the Internet, just like the ARM or the laptop in figures on pages 7 and
8 respectively connect their modem or USB dongles. The CPE, just like
the ARM, or like the laptop, will run a DHCPv6 Prefix Delegation Client.

We could describe that CPE-with-LTE in a new figure, if necessary. But I 
would request to be hinted by someone explaining that DHCPv6_PD on CPE 
with LTE interface was tried and it worked with a /56.

(there are a few kinds of CPE using LTE to go to Internet: either use an
internal LTE modem card, or an USB dongle or maybe a user's smartphone;
in this latter case the DHCPv6-PD Client would not run on the CPE but on
the smartphone, and so there would be more differences than what we
describe in the draft; so only someone who tried DHCPv6-PD on CPE with
cellular and made it work would hint about how it worked).
