Could you be more specific where exactly it is required? Example in
manual page does not set any MAC; do you imply that this example is
non-functioning?
Example 3. A bridge with two enslaved links
# /etc/systemd/network/25-bridge-static.network
[Match]
Name=bridge0
[Network]
Address=192.168.0.15/24
Gateway=192.168.0.1
DNS=192.168.0.1
# /etc/systemd/network/25-bridge-slave-interface-1.network
[Match]
Name=enp2s0
[Network]
Bridge=bridge0
# /etc/systemd/network/25-bridge-slave-interface-2.network
[Match]
Name=wlp3s0
[Network]
Bridge=bridge0
This creates a bridge and attaches devices "enp2s0" and "wlp3s0"
to it. The bridge
will have the specified static address and network assigned, and
a default route via
the specified gateway will be added. The specified DNS server
will be added to the
global list of DNS resolvers.
