Clients not getting IPv6 addresses

I have enabled dual stack on my network. My controller is only doing layer 2 and the clients gateway is on Laer3 switch. DHCP server is setup to assign both IPv4 and IPv6. Clients are getting IPv4 addresses but IPv6 is not working. I hae enable IPv6 mld on controller. The AAA profile is allowing IPv6 traffic. 

 

I am not sure where the problem is. Any help or tips for troubleshooting this issue?

Have you also enable IPv6 globally on the controllers?

Yes DMO is enabled. Also "Drop Broadcast and Unknown Multicast" is enabled. I guess it is a multicast related issue but I am not sure.

I think drop unknown multicast should be disabled but not sure. Have you a custom valid user acl?
