IPv6 on ATT Fiber

[lrosenman]

I'm trying to follow this article:
https://forums.att.com/conversations/att-internet-email-security/ipv6-wan-address-125-block/60206fe564100a03adc851bc?page=2

and have the following dhcp6c.conf:
# Setup requests for the WAN interface.
interface em4 {
   # Request a single IPv6 address for WAN interface (RG responds with 2600:1702:xxxx:yyy0::48)
   send ia-na 10;
   # Request 8x /64 prefix delegations:
   send ia-pd 0;
   send ia-pd 1;
   send ia-pd 2;
   send ia-pd 3;
   send ia-pd 4;
   send ia-pd 5;
   send ia-pd 6;
   send ia-pd 7;
   send rapid-commit;
   request domain-name-servers;
   request domain-name;
   script "/var/etc/dhcp6c_opt5_script.sh";
   #script "/conf/set_wan_static_v6.sh";
};
# These blocks are required, and I should probably
# assign the prefixes to the LAN interfaces here.
# Since my /60 has not changed since I implemented
# this, I treat them as static and assign them as such.
id-assoc na 10 { };
id-assoc pd 0 {
   prefix-interface em0 {
      sla-id 8;
      sla-len 8;
   };
};
id-assoc pd 1 { };
id-assoc pd 2 { };
id-assoc pd 3 { };
id-assoc pd 4 { };
id-assoc pd 5 { };
id-assoc pd 6 { };
id-assoc pd 7 { };
#

the em0 interface doesn't seem to get an IPv6 address, and I'm not 100% certain I'm actually getting the PD.

Can anyone help me with:
1) how do I get dhcp6c to log something?
2) what am I missing?
3) getting radvd configured and running.

Thanks, as always.

https://forum.netgate.com/topic/153288/multiple-ipv6-prefix-delegation-over-at-t-residential-gateway-for-pfsense-2-4-5/18 <-- this works for us as well (so far at least on one interface).
