option 61?
Don't need anything on the CPE. OLT can insert GEM port details / ONT serial to identify punter. Traffic in a CVLAN in turn encapsulated in an SVLAN for delivery to the ISP.
Can do similar on VDSL or ADSL, and indeed BT Wholesale documentation gives details of the DHCP options they insert with their IPoE offering.
YouFibre know which connection is mine without any kind of authentication from me. They know the ONT I have, which port it's on on which chassis and line card, the GEM port that's produced at connection time.
Have a looksie at https://www.openreach.co.uk/cpporta...e/help-and-support/sins/documents/SIN_506.pdf section 2.1.8 - Openreach put all the relevant cool stuff into option 82 including a comprehensive circuit ID.
