SOLVED: dhcrelay - IPv6

I have setup DHCP Relay agent and have an IPv6 DHCP server running on a different system.

It appears DHCP Relay is working, however, my clients don't get a gateway for IPv6 address. If I set the Gateway manually on the clients, then IPv6 fully works.

How do I get the DHCPRelay agent to broadcast the gateway? I know for IPv6 this has to be done at the "Router/Gateway" level, and I'm using CentOS 7 as my Gateway.

I treid adding option 0021 (Gateway) to my DHCPv6 server, but it's ignored.

Any thoughts?

eth0: WAN (IPv6 DHCP)
eth1: LAN (IPv6 Static IP)
