I have followed a number of online guides on setting up Centurylink IPv6 6rd on various routers. I tried the exact same approach on my RV340 and cannot get it to establish an IPv6 connection. The settings are attached. I did wonder if a "DHCP-PD" prefix is needed?
I have the connection type set to SLAAC. Centurylink says their IPv6 6rd is "stateless". I have also tried DHCP and still no luck.
My IPv4 IP is dynamic, DHCP, has worked fine for years now. Connection type is gigabit fiber.
