I would like to give everyone a heads up, we are changing the allowed shortest prefix from /60 to a /64. There is an issue found on a version of CMTS code that creates an issue for the CMTS. Once all the CMTS's get upgraded to the latest code we will change the shortest prefix back to a /60.
So if you have a IA_PD request as a /60 the DHCP server will respond with a /64. So leave your IA_PD request as a /60 once we get the code in the field and change the DHCP back your request will be honored.
If you have any questions please feel free to PM me if you want. I will answer what I can; as you all are aware.
Thanks for the heads up. I suspect that I must have gotten caught up in the middle of the config changes yesterday: »[IPv6] IPv6 problems with router's factory MAC address
After reading your post, I tried the DIR655's original WAN MAC address again, and now it works again (with a "/64" allocation).--
