Documented steps

Create the network with the l3 mode flag, e.g. docker network create -d ipvlan --subnet=192.168.210.0/24 --gateway=192.168.210.254 -o ipvlan_mode=l3 -o parent=eth0 l3net
Attach containers and assign static addresses per subnet as needed.
Confirm broadcast/multicast traffic is not forwarded between endpoints.

Known gotchas

l3 mode drops all broadcast and multicast traffic - ideal for very large scale but it can break protocols that rely on broadcast/multicast discovery.
It eliminates bridging loops and reduces the failure domain to the local host only.
Route distribution across a cluster of hosts is beyond the initial driver implementation - you must manage routes yourself.
