- | Starting from an active IPv6 ADsL connection, let us analyse a typical Router Advertisement (RA) packet sent by a NeufBox. IPv6 routers (here the NeufBox) send unsolicited Router Advertisement messages pseudo-periodically and solicited Router Advertisement messages in response to the receipt of a Router Solicitation message. The Router Advertisement message contains the information required by hosts to determine the link prefixes, the link MTU, whether or not to use address autoconfiguration, | ||
