28.5 Creating a Network Manager 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
