There are at least two reasons so far: - the router wishes to advertise the prefix for use by stateful address autoconfiguration, but wishes that all packets be sent via the router. (The router then has the option to redirect to hosts that are on-link.) - the router includes a prefix information option in order to present the router's own global address (using the R-bit defined in RFC 3775 section 7.2) and the global address doesn't fall in one of the on-link prefixes.
