Need to restart radvd after boot to get ipv6 prefix advertisement on LAN

[sclevine]

After upgrading from 22.7 to 23.1, I need to restart radvd in the web interface to get ipv6 PDs from my WAN to appear in /var/etc/radvd.conf. Before restarting radvd, I only see virtual IPs that I've assigned to the interfaces. After restarting it, I see virtual IPs along with the prefixes delegated from the WAN.

My LANs all use "Unmanaged" RAs with no DHCPv6 server running. I've also tried "Stateless" with no improvement.

I'm on AT&T fiber with a custom configuration (similar to https://github.com/lilchancep/att-pfsense-ipv6) to request four separate /64s from my BGW320. I had to patch a heap overflow in dhcp6c to make this stable in 22.7 (https://github.com/opnsense/dhcp6c/pull/33) but this issue is separate, and still occurs without the patch.

Seems like something should call dhcpd_radvd_configure after the prefixes are assigned to the interfaces?

Confirming this is fixed in 23.1.2

Glad to hear. I haven't gotten around to give dhcp6c client more attention. It's been quite a bit of work for the overall scope of 23.1 and 23.1.2 seems like it does bring this to a desirable state and make room for other work.
