23.2 Creating a Network Bridge from the Command-Line
The first step in creating the network bridge is to add a new connection to the network configuration. This can be achieved using the nmcli tool, specifying that the connection is to be a bridge and providing names for both the connection and the interface:
# nmcli con add ifname br0 type bridge con-name br0
Once the connection has been added, a bridge slave interface needs to be established between physical device eno1 (the slave) and the bridge connection br0 (the master) as follows:
# nmcli con add type bridge-slave ifname eno1 master br0
At this point, the NetworkManager connection list should read as follows:
# nmcli con show
NAME UUID TYPE DEVICE
eno1 66f0abed-db43-4d79-8f5e-2cbf8c7e3aff ethernet eno1
virbr0 0fa934d5-0508-47b7-a119-33a232b03f64 bridge virbr0
