Updates after a day of research and discussion with JTAC.... JTAC say there were known issues with how jdhcpd handled client-identifier and that caused these issues. That was fixed in junos:19.2R3 junos:19.3R3 junos:19.4R3 junos:20.1R2 junos:20.2R2 junos:20.3R1
There were reports that the order that the DHCP options were listed was causing problems. Packet captures from our SRX seem to rule that out, they look fine. Another forum says the SRX has a 255 end of option.. option, and that causes the problem but all vendors I have checked today also sent that... so dont think thats it. I've received two reports of it working for people without any issues, and 2 reports of it having issues. The firmware versions that it works fine on are both different and one of them is even 15X. I can't find any PR's to match what I am seeing so I can only assume they are private. PPPOE seems to be fine across the board on HFC. Putting down as many notes here as possible so next time someone is trying to get a link up like this there is some reference material to go off. I have to wait until late next week for the end client to update their SRX to a newer code base inline with what JTAC say so until then I can't put this issue to bed.
