Basic Bridge Configuration Using nmcli

The following table shows a simple example of how to create a virtual bridge on Linux and how to add TAP interfaces to it using nmcli commands (NetworkManager command-line interface):

StepDescription
Gather information about the existing network configuration.


List all existing interfaces, their status and their MAC addresses:
   # ip link show

List all configured IP addresses and netmasks:
   # ip addr show

List the routing table entries:
   # ip route show

If needed, create a new connection for the physical interface to be used with the bridge.

# nmcli conn add type ethernet autoconnect yes \
con-name
<physical-int-name> \
ifname <pysical-int-name> ip4 0.0.0.0

If needed, create a bridge and set a static IP address for it.# nmcli con add type bridge autoconnect yes \
con-name
mybr0 ifname mybr0  \
ipv4.method manual ip4
<ipaddr/mask> stp off
If needed, activate bridge.# nmcli con up bridge-mybr0
If needed, add physical interface to bridge.# nmcli conn modify <physical-int-conn> master mybr0 \
slave-type bridge
Activate changes to interface.# nmcli conn up <physical-int-conn>
