Please enable the following options:

CONFIG_IPV6_ROUTER_PREF=y
CONFIG_IPV6_ROUTE_INFO=y

Routers configured according to RFC 6204 must advertise routes using the "Route Information Option" defined in RFC 4191. If desktops/servers running Ubuntu don't support this option, they may fail to route local IPv6 networks in the absence of a default route.
