Address Auto-configuration
1. Auto-configuration: Disable or enable this auto configuration setting.
2. Auto-configuration Type: You may set stateless or stateful (Dynamic IPv6).
3. Router Advertisement Lifetime: You can set the time for the period that the
router send (broadcast) its router advertisement. Each router periodically
multicasts a Router Advertisement from each of its multicast interfaces,
announcing the IP address of that interface. Hosts discover the addresses of their
neighboring routers simply by listening for advertisements. When a host attached
to a multicast link starts up, it may multicast a Router Solicitation to ask for
immediate advertisements, rather than waiting for the next periodic ones to arrive;
if and only if no advertisements are forthcoming, the host may retransmit the
solicitation a small number of times, but then must desist from sending any more
solicitations. Any routers that subsequently start up, or that were not discovered
because of packet loss or temporary link partitioning, are eventually discovered by
reception of their periodic (unsolicited) advertisements.
