Hi Chris, all
I am struggling the same problem too, and here is my working
configuration for dhcp6c in my test environment.
Hope this can be help.
vtnet0 is uplink, where I expect to receive RA from ISP.
If upstream router send RA with PD with 2001:db8:beef::/56, dhcp6c
will add sla-len (8 in this configuration) to the prefix length (/56)
to get the final prefix length of /64.
Also, dhcp6c will add sla-id (11 and 12, decimal) to prefix, so that
I will use 2001:db8:beef:b/64 and 2001:db8:beef:c/64 for assigning my
internal network interfaces (vtnet1 and vtnet2).
Well, I am wondering how I can tell "authentication isp_auth" entry to
use the "isp_key", especially when I have multiple "keyinfo" entries.
= /usr/local/etc/dhcp6c.conf =
keyinfo isp_key {
realm "example.org";
keyid 1;
secret "JTY0XXX=="; # masked.
};
authentication isp_auth {
protocol delayed;
};
interface vtnet0 {
script "/usr/local/etc/dhcp6c-script.sh";
send ia-pd 3;
send authentication isp_auth;
request domain-name-servers;
request domain-name;
request ntp-servers;
#send rapid-commit;
};
id-assoc pd 3 {
prefix-interface vtnet1 {
sla-id 11;
sla-len 8;
};
prefix-interface vtnet2 {
sla-id 12;
sla-len 8;
};
};

Thanks and Best Regards,
