In my opinion, there should be a router or firewall between the master radio and the rest of the automation or enterprise network, for exactly this kind of reason.
Once you've got an enterprise network that includes ordinary Windows workstations, or printers, or WiFi access points, or anything with Universal Plug and Play, the amount of multicast and broadcast traffic can be substantial. If you happen to have multicast I/O, it can get huge.
I once got thrown off a job shortly after showing the customer that their printer discovery traffic from Downtown was showing up over the radios at their remote pump stations.
There are certainly commercial routers and firewalls that do this sort of thing, as well as sturdy open-source stuff like PFSense.
