Does IPv6 support 802.1q. Can I request a tagging packet to my IPv6 server?

I have a modem with IPv4 and IPv6 configurations. And in my Cisco BRAS iOS server have a IPv6 configurations.

 

 

My topoly is BRAS server(DHCPv4 adn DHCPv6 server) --> L2 cisco switch --> Modem

 

I am configuring the modem like tagging WAN and I cannot get IPv6 from DHCPv6 server but I can get the IPv4 IP from DHCPv4 server. I have configured my port in switch as Tagged/Trunk. But I can't get IP from DHCPv6 server in tagging config. 

 

Here is my DHCP pool config and Interface config in my server.

 

ipv6 unicast-routing
ipv6 source-route
ipv6 cef
ipv6 dhcp pool STATEFUL
address prefix 2001:1111:1111:1234::/64
dns-server 2001:4860:4860::8888

802.1q doesn't "care" about IPv4 or IPv6 because 802.1q is Layer 2.

Hello @Arutkavi

What was the issue and most of all how have you fixed this issue because i'm facing the same problem :  i can get an ipv4 address but not an ipv6 address, using statefull dhcp, via a trunk port.

thanks for you help
