Setting 'ra=true' will enable auto-configuration of IPv6 addresses, and of the Default Route.
You may also wish to configure IPv6 DNS servers ( DNS servers that are to be queried over IPv6 ).
There are a couple of different mechanisms available to push out IPv6 DNS servers, and the FB2700 supports both.
Be sure your DNS server actually responds on it's IPv6 address!
The first method is to have the FB include the DNS server addresses as a new option( RDNSS ) in the Router Announcements. ( RFC6106 ).
RFC6106 aware clients are, however, somewhat thin on the ground at the moment.
To enable this, set the 'ra-dns' option to point to your IPv6 Recursive DNS Server.
In this example, I'm pointing it to a DNS server on 2001:8B0:B7:1::2.

Most clients are not currently able to recieve this option.
So we
Setting the 'O' flag in the RA, telling the client to do DHCPv6

Now, the FB will set the 'O' flag in the RAs,
You must provision an external DHCPv6 server to respond to these queries.
The FB can be also be configured to run a mini-DHCPv6 server to respond to these queries by itself,
To enable the 'O' flag AND the mini-DHCPv6, set the ra-other option to 'dhcpv6', and also specify the DNS server address to be doled out in the rd-dns option:
