advertise-inactive only advertises inactive BGP routes. So it won't
advertise an aggregate if it is inactive.

But you can advertise the interface route when active and the
aggregate when the interface goes down... all you need to do is accept
that prefix indepedently of the originating protocol.

A static discard will less preference will also do the job.

Again, as Gary mentioned, the potential drawback is that you may be
attracting traffic that is going to be droped while there may be an
alternate route in the network, when advertising a discard route.
