This creates a podman network using an existing bridge interface on the host. In this case, it is used to directly attach the container to a VLAN 24, in which the host has otherwise no IP connectivity.

1. Create the above file as /etc/cni/net.d/vlan24.conflist
2. Confirm the configuration with sudo podman network inspect vlan24
3. Run a container on the network podman run -d --network vlan24 docker.io/nginx
4. Try connecting to the container curl -I http://10.11.0.17

Note that only one container can be started with the configuration above, which uses a single IP address. This can probably be expanded with specifying a network address and an additional range for the IP address leases.
