Help setting up Orbi RBR850 for use with CenturyLink IPv6

I have Centurylink Fiber with an Orbi RBR850 hooked directly to the ONT. CL uses 6rd for their IPv6. OF WHICH it use to work really great until about halfway through the v3.x firmware. So if you are runnning anything in the late v3s to v4s it won't work well. Meaning, lots of restarts. Which, right now, is the only way I can find to get it back. NG knows about it and what is being done, who knows. Also Apple gear tends create its own IPv6 address. I have been using it for LAN networking for decades before they started using it on net.

CL's IPv6 Servers Address are universal. Use what I have in the screen shot and use default settings for acquiring the DNS.

Hope this helps . . .
