Router advertisements are exactly what the name suggests, routers advertising their presence. The first function of router advertisements is to tell hosts where the routers are,
OK, so far.
so the hosts can install a default route.
WRONG. Routers are not "a default route". If a host receives RAs only from a router, the host can do nothing other than installing the router as the default router. If not, however, the host must directly be involved in IGP activities, or, the following end to end argument is applicable: The function in question can completely and correctly be implemented only with the knowledge and help of the application standing at the end points of the communication system. Therefore, providing that questioned function as a feature of the communication system itself is not possible. Masataka Ohta PS Granted that the notion of default router of IPv4 is no better than that of IPv6.
