We’re modelling two different things here. One is a physical system that we can have run multiple logical systems (think a bare metal machine running multiple VMs), and then the other is a logical separation of solely routing tables within one of the logical systems (think Linux network namespaces). There are N logical systems to each physical system, and M routing tables (VRFs) to each logical system. A logical system might come with its own set of protocol daemons, authentication etc., whereas a VRF typically would not.
