IPV6 PD Support?

Hello all - 

 

I have been in the trial for about 10 months and have been mostly unable to use the service since I can't set a static route or request a PD larger than /64 from my Netgear trial box. I posted several times last November in an effort to get something going but the firmware just wasn't there yet.

 

I've circled back to the project and now find that I am running firmware 1.34.04 on the cable modem/router but that I am still unable to hint a PD larger than /64 or set a static route.

 

(In other news, my regular service SMC modem appears to have much more IPV6 functionality now but nothing enabled as I have static IPV4... Dang!)

 

Should I expect to be able to hint a /60 from the Netgear now? Is there any plan to include static routing in the firmware? (Which, by itself, would solve all of my problems as I have an ASA5505 for a firewall/router behind the cable modem)

 

Thanks!

Re: IPV6 PD Support?

It looks like things start working if you get firmware V3.01.04. I believe they're in the process of rolling it out.

Re: IPV6 PD Support?

My netgear trial ipv6 modem is also running fw V1.34.04 (and has an uptime ~2 months, so it has been this way quite a while).

 

Is there some trick to getting newer firmware onto it?

 

It's not actually useful for anything with the current firmware.

Re: IPV6 PD Support?

And approximately 30 hours ago my netgear ipv6 test cable modem got updated to firmware version v3.01.04

 

So it seems like there's a rollout in progress.

 

(I've yet to test whether PD works though)

Re: IPV6 PD Support?

Preliminary testing suggest PD is functional now.

 

My setup is currently a little busted and thus I can't do proper testing, but I've confirmed that:

- I can now get a stateless DHCP reply (no change),

- and a stateful pd lease (for a /60 and apparently for 60 seconds)

- and ping6 from the outside internet for both the /64 and the /60 reach the relevant machine.

 

(unfortunately due to how I had to hack this into submission, I can't test the outgoing path without mucking with source routing which I don't have the heart for atm)

Re: IPV6 PD Support?

And in case anyone is curious, here's the scripts/setup I've been using to test/debug this.
