¿µ¹®³»¿ë¿ä¾à According to [RFC 3056], there are two deployment options for a 6to4 routing domain, depending on whether or not the domain is using an IPv6 exterior routing protocol. If a routing protocol is used, then the 6to4 routers acquire routes to all existing IPv6 networks through the combination of EGP and IGP. If no IPv6 exterior routing protocol is used, the 6to4 routers using a given relay router each have a default IPv6 routing pointing to the relay router. This second case is typically used by small networks; for these networks, finding and configuring the default route is in practice a ignificant hurdle. In addition, even when the managers of these networks find an available route, this route often points to a router on the other side of the Internet, leading to very poor performance. The operation of 6to4 routers requires either that the routers participate in IPv6 interdomain routing, or that the routers be provisioned with a default route. This standard proposes a standard method to define the default route.
