Comcast IPv6 decided to bork itself again. Nothing I've tried (restarting DHCPv6 client, power cycling the modem) works.

My router gets a v6 address, can hit the internet without issues.

Router makes a DHCPv6 request, gets a delegated /59 out of my static /56.

But when I try to use an address out of the /59 on the local network (via radvd handing out /64's) it gets nowhere, traceroutes stop at the CPE/CMTS.

@azonenberg Try sending a prefix delegation request for the /56 in the DHCPv6 request -- even if it's a static allocation.

@GyrosGeier I've been doing that (actually multiple separate /59 requests since the CPE won't let me request a /56 in one go because derpy bugs).

The config used to work, I changed nothing on my end. I still get the DHCPv6-PD reply coming back saying the CPE is delegating the /59 to me, but it's not actually routing anywhere.
