Can RA advertize for specific routes without advertising a default route

[severach]

I'd like RA to advertise itself for the route FD00::/64.

I'd like RA to NOT advertise itself as the default route.

Is this possible? Right now I have the clients configured with static IP and custom routes.

I put FD00::/64 in the RA Subnets and specified "Router Only". RA advertised itself as the default to the local subnet. If FD00 refers to the subnets to be advertised to, that didn't work. If FD00 refers to the subnets to be advertised for, that didn't work either.

edit–
Even worse, when I set the Router mode back to "disabled", my custom route on the client was erased. This might be a client problem.
