Thank you very much for clarificaion.

If there is daemon-installed route (learned dynamically), there should be a=
 way
to overrided it with manually installed route. I'm sure "route delete/route
add" is racy and won't work because of daemon re-installing its route.

Will "route change" do the job reliably in such case?
