-A Bridged networking is nothing but a simple technique to connect to the outside network through the physical interface. It is useful for LXC/KVM/Xen/Containers virtualization and other virtual interfaces. The virtual interfaces appear as regular hosts to the rest of the network. In this tutorial I will explain how to configure a Linux bridge with bridge-utils (brctl) command line utility on Ubuntu server.
+顾名思义，网桥的作用是通过物理接口连接内部和外部网络。对于虚拟端口或者 LXC/KVM/Xen/容器来说，这非常有用。通过网桥虚拟端口看起来是网络上的一个常规设备。在这个教程中，我将会介绍如何在 Ubuntu 服务器上通过 bridge-utils(brctl) 命令行来配置 Linux 网桥。
