Set the bridge name and select the ports as shown in the following screenshot. Choose Networking in Cockpit Web ConsoleĪ pop window with options to add a new bridge will appear. To add a bridge, go to Networking, then click Add Bridge as highlighted in the following image. To interact with the system’s network configuration, the cockpit uses NetworkManager and the DBus APIs it provides. The cockpit is a lightweight, interactive and easy-to-use web-based server administration interface. # man nmcliĬreating a Network Bridge via Cockpit Web Console

# nmcli conn up Wired\ connection\ 1įor more information, see the nmcli manual page. Note that you first of all have to activate the wired connection. To deactivate the bridge connection and delete it, run the following commands. Next, use the following bridge command to display the current bridge port configuration and flags. Now when you try to list the active network connections on the system, the bridge connection should display on the list. Then deactivate or bring down the Ethernet or Wired connection. Next, bring up or activate the bridge connection, you can use the connection name or UUID as shown. # nmcli conn add type ethernet slave-type bridge con-name bridge-br0 ifname enp2s0 master br0Īdd Ethernet Interface as a Slave to Bridge

Now add the Ethernet interface (enp2s0) as a portable device to the bridge (br0) connection as shown. To set a static IP address, run the following commands to set IPv4 address, network mask, default gateway, and DNS server of the br0 connection (set the values according to your environment). Note: In a bridged mode, the virtual machines are easily accessible to the physical network, they appear within the same subnet as the host machine and they can access services such as DHCP. # nmcli conn add type bridge con-name br0 ifname br0 Next, create a network bridge interface using the following nmcli command, where conn or con stands for connection, and the connection name is br0 and the interface name is also br0.

Important: If the libvirtd daemon ( libvirtd) is installed and started, the default network interface that represents the network bridge (virtual network switch) is virbr0 as seen in the above screenshots. Next, to list the active network connections on the test system, use the following nmcli command. # ip addįrom the output of the above command, the Ethernet interface is called enp2s0, we will add this interface to the bridge as a slave. This guide shows multiple ways to set up a network bridge in RHEL/CentOS 8 and use it to set up virtual networking in a bridged mode under Oracle VirtualBox and KVM, to connect Virtual Machines to the same network as the host.įirst, use the IP command to identify the network interfaces (both physical and virtual) currently attached to your machine and the networks they are connected to.

There are several use cases of network bridging, one practical application is in a virtualization environment to create a virtual network switch used to connect virtual machines (VMs) to the same network as the host. The bridge serves a similar function as a network switch it acts more or less like a virtual network switch. Linux operating systems such as RHEL ( Red Hat Enterprise Linux) and CentOS 8 support the implementation of a software-based network bridge to emulate a hardware bridge.

It forwards traffic based on the MAC addresses of hosts (stored in a MAC address table). It creates a single network interface to set up a single aggregate network from multiple networks or network segments. A network bridge is a data-link layer device that interconnects two or more network segments, offering communication between them.
