Quagga fully supports IPv6 routing. As described so far, Quagga supports
RIPng, OSPFv3 and BGP-4+. You can give IPv6 addresses to an interface
and configure static IPv6 routing information. Quagga IPv6 also provides
automatic address configuration via a feature called
auto configuration. To do it, the router must send router advertisement
messages to the all nodes that exist on the network.
