A network bridge is a logical device that forwards traffic between connected physical interfaces based on MAC addresses. This kind of bridge can be used to emulate a hardware bridge in virtualization applications, such as KVM, to share the NIC with multiple virtual NICs.
To bridge two physical networks, we need two network interfaces. Your physical interfaces should never be configured with any address as the bridge will be configured with the IP address(es).
For the sake of ease, the physical network interfaces we will bridge are
