Hello,
I have an edgerouter lite 3 running octeon for the past few years.
The connection is dual-stack. On the ipv6 side, there's two prefixes:
for the ND side, a /64 let's call it 2a02:8011:
for the DP (delegation prefix) it's a /48 let's call it 2a02:8010.
v6 IPs from the /48 are distributed to the DMZ.
on the edgerouter:
cnmac2 is not used
cnmac0 points to the dmz and has ipv4 assigned manually
pppoe0 is on cnmac1 and it always has, as expected, ipv6 from the ND prefix.
cnmac1 points to the dmz and has ipv4 and, normally, ipv6, and the ipv6 would
be
from the PD prefix.
This *used* to work and stopped working sometime while at 7.3.
It's at 7.4 now. Sometimes it would stop working and a reboot would fix it.
I'm unsure if it's a misconfiguration at my end or if it's an ISP problem.
The problem persists even if pf is stopped.
Please can anyone advise?

The problem is cnmac1 isn't getting its DHCP-DP /48 as expected.
It does get an ipv6 but it's
inet6 fe80::f29f:c2ff:fe10:488f%cnmac1 prefixlen 64 scopeid 0x2
and that's it.
