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):
| Step | Description |
|---|---|
| If needed, create a bridge and set a static IP address for it. | # nmcli con add type bridge ifname mybr0 ipv4.method manual ip4 <ipaddr/mask> |
| 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> |
After the bridge has been created, you can use the initialize command in the emulator configuration to add the required TAP interfaces for the emulator to the bridge.
