IPv6 and the Cisco DPC3941B
I have a business account. I have a situation with a customer in Asia wherein I need to get this working. Can anyone confirm that this device (Cisco DPC3941B) will work/respond appropriately with v6 PD request? I can see the device itself has a /56, has taken a /64 for itself, and i can ping devices from the gateway, but cannot seem to get it to delegate. In my case I have Ubiquiti EdgeRouter, but I have tried others as well. I also tried to get it running using private IPv6 space on the interiour, but it appears I cannot get enter a static route for v6 on the device. I've seen notes on various forumns that suggest the Cisco device will not work, or needs to be on a special version. I'm looking for some confirmation one way or the other.
I am a network engineer by trade, and while perhpas not a v6 ninja, do know my way around an IP stack. Any insights would be appreciated.
