IPv6 / DHCPv6 with S350 Smart Switches (GS324T / GS348T)

WilsonS,

I have tested it and it works in my case for internal LAN and external WAN with IPv6 DHCP and forwarding of IPv6 packets.

Enable IGMP snooping globally.

Enable IGMP snooping on the VLAN that DHCPv6 packets are forwarded.

Enable Multicast Router on the ports where DHCP server and clients are connected (in my case all 52 including ISP WAN)

Check the MFDB Table for forwarding Interfaces and test IPv6 connectifity after fresh DHCP request:

Thanks for the solution and best regards!

Same issue here with a Netgear GS324T, SW 1.0.0.43
I have really looked everywhere why IPv6 did not work... and finally landed here.
Snooping is globally deactivated and this does not make it work, need to check if globally enabling it and globally enabling routing to all ports does make it better (because everyone should get Dual Stack).

Ok, a quick check later and it does not work.

I have done the changes as suggested by koeber 

My network of Dual Stack clients is actually very flat, so only VLAN 1 needs to be enabled. MFDB Statistics only shows a "01:00:5e:7f:ff:fa" MAC, which is not one of my devices. I tried several configurations and changes, but seems like this switch does not work. How to solve that bug?

After trying for some time I got it working - which was nice.

Sadly the solution does not survive a reboot of the switch.

With that I guess there is nothing more to do than scrap the switch and look for another vendor?

I'm working on this issue. 

Thank you WilsonS - so is it planned to deliver a software patch to fix this issue?

Thanks

WilsonS Any updates to the issue?

Thanks a lot

It's planned to deliver a software patch to fix this issue. 

Awesome WilsonS - thats good news. Can you give us an ETA and/or write in this thread as soon as it is released? Thank you!
