Setting ipv4.routes with next hop?

I have multiple containers, each of which has an IP subnet behind it. (Imagine: each container is a router, and behind that router are other things. Actually more containers, but that doesn’t really matter)

So I need to add static routes to reach those behind-the-container networks.

In that respect, you would try to avoid setting static routes.
Have a look at GitHub - FRRouting/frr: The FRRouting Protocol Suite
There has been a discussion on frr recently and @bodleytunes may be able to point you to the correct direction.
