Starting with 1.3-rolling-202007251937 (it works in 1.3-rolling-202007251937), the list of prefix-delegated interfaces dhcpv6_pd_interfaces never makes it to the template in /usr/share/vyos/templates/dhcp-client/ipv6.tmpl.
I believe the change likely related to the get_config_dict() changes in T2653 that were merged on July 25.
To demonstrate, as far as I can tell, have any config with DHCPv6-PD, such as:
...
interfaces {
ethernet eth0 {
address 1.2.3.4/29
address dhcpv6
dhcpv6-options {
prefix-delegation {
interface eth1 {
address 1
sla-id 1
sla-len 4
}
interface eth2 {
address 1
sla-id 2
sla-len 4
}
}
ipv6 {
address {
autoconf
}
}
}
ethernet eth1 {
address 192.168.1.1/24
}
ethernet eth2 {
address 192.168.10.1/24
}
}
...And then note the following contents of /run/dhcp6c/dhcp6c.eth0.conf:
# generated by dhcp.py
# man https://www.unix.com/man-page/debian/5/dhcp6c.conf/
interface eth0 {
request domain-name-servers;
request domain-name;
send ia-na 1; # non-temporary address
};
id-assoc na 1 {
# Identity association NA
};There's no send ia-pd 2; # prefix delegation or id-assoc pd 2 { section, so it seems like the new config code isn't propagating the dhcpv6_pd_interfaces value to the _DHCPv6 class in vyos/ifconfig/dhcp.py from vyos/ifconfig/interface.py.
I also tried setting int eth eth0 dhcpv6-options temporary just to see if that made it to the config file. It did not.
