I can't help you with Inspire, but this may be of some help? It's what I used to use for my ADSL2 PPPoE back in Sydney.

There's also this: http://www.ifm.net.nz/cookbooks/890-isr-wizard.html

Thanks for those. I have already looked at them and tested it based on what I saw, but the upshot is without further information from Inspire I am basically flying blind.

I had a UFB service with IPV6 previously from them - and used that config as a template - but it doesn't work. Whether they have done something different for VDSL or changed something in the interim....? I don't know.

Considering the cost of the service is over $150 / month, I think getting a working config template from them is a reasonable request.

http://ipv6.inspire.net.nz/ suggests they do DHCPv6 PD over PPPoE, just like Internode (and Snap/2d). Have you contacted their ipv6 email address?

I have been supposedly issued a /56 of IPV6 space and used what would appear to be the appropriate config but it just doesn't work. I don't know why.

I assume you have VLAN10 trunk on the WAN side?
Our (Chorus) Wholesale VDSL service needs this.

you also need to make sure everything is 802.1p=0  Some devices will default mark control protocols as another pbit... at which point our DSLAM will discard it.

Yes. IPV4 connectivity works.

MadEngineer: Email or phone them - they are probably NZs most helpful isp.

Could be but IPV6 falls into no man's land.

Drop me an email with your contact details and I will get someone in the NOC to have a chat to you early next week to see what we can do to help.  IPV6 isnt something the helpdesk is likely to be able to help with too much at this stage I am afraid, we need to go a few levels lower in the building to where we lock away the IPV6 people, they seem to be afraid of sunlight
