I am receiving a /56 PD/Route from TWC and a /64 for autoconfiguration.
This sounds really nice. Until I attempt to assign an IP address that is outside the /64 but within the /56 route.
I get a "Source address failed ingress/egress policy" ICMPv6 failure.
The RA from TWC is clearing broadcasting a /56 route.
Is TWC/Spectrum blocking but still offering a /56 PD?
Or is this breakage?
If it's a TWC leased device, Call TWC, lol... Good luck getting transferred to tier 3 to get a correct answer for your configuration and zip code.
There are unresolved issues with IPv6, my last recollection was that only /64 was supported.
If it's a COAM unit, good luck, use whatever works, twc will blame it on the device you purchased.
Post your zip code.
some areas have really poor IPv6 ping time/ DNS resolution time and simply time out.
Are all devices on your lan Ipv6 or are some IPv4? the latter is an issue as well.
