Another broken dhcpv6-pd complaint on brand new DPC3939B

I, too, am having the prefix delegation neighbor discovery issue noted in this post. My Cisco DPC3939B modem worked flawlessly for years but a few months ago started randomly rebooting. I expected the PD to change since the DUID requesting the prefix would be different, but what I did not expect is that IPv6 would stop working cimnpletely. 90% of my traffic is v6 (yes, I have tracked it for years), and now the entire network is a dunpster fire since I no longer have any IPv6 connectivity. My router does not support ndp-proxy, so I am now stuck with a completely broken network. I would have suffered through the rancom reboots had I known this would have been the result of a CPE replacement. My old one must have had an older firmware build, as there are some other subtle differences - but I need this fixed, a pretty big part of my job involves working with IPv6 and this complete lack of it is literally costing me productivity.

I have done so no less than 8 times via this forum, twitter direct messages, and phone calls. Will doing it again yield anything different? I suspect not. 

My experience with your v6 support is that when it works, it works well and is touted very highly as a forward looking feature. However, this devolves extremely quickly and any questions about it (IPv6) in any detail are sent to a meat grinder of random guessing or total non-response. 

While I recognize that v6 yields the company no more profit, and is something that 99.5% of customers largely don't know or care about, I would still expect some level of help - or at the very least official acknowledgment that it won't work. 

At least knowing officially that it is not going to work would stop folks from spending time on it. 

 

At this point I have been forced to move back to a HE tunnel and generate VPNs that transit IPv6 like it's 2008 again. What a waste of time.

I know that it's been frustrating and we're going to work on getting this definitively figured out for you. If you're able to send a private message to verify the account so we can provide any account specifics that may be needed, that would be appreciated although we will be glad to provide any general information that we have here as well.
