附录A
Linux
高级联网
第
3
章讨论过一些基本的
Linux
联网概念。本附录将以第
3
章的内容作为基础，讨论一些
高级的
Linux
联网概念和配置。
本附录将介绍以下几个主题。
•
使用
macvlan
接口
•
虚拟机联网
•
使用网络名称空间
• Linux
容器联网
•
使用
Open vSwitch
以上主题中有几个主题都能独立成书了。因此，本附录并不会全面深入地讨论这些主题。
相反，我们将专注于提供足够的信息，让你了解其在整个联网领域中所处的位置。除此之
外，还会介绍如何安装、配置或管理这些联网配置的基础知识。
下面就从使用
macvlan
接口开始吧。
A.1
使用
macvlan
接口
macvlan
接口有点儿像第
3
章讨论过的
VLAN
接口的反面。
VLAN
接口允许一个物理接口
在多个
VLAN
（广播域）中同时通信
，可以将其视作“多（网络）对一（物理接口）”的
关系。而
macvla
n
接口允许在单个广播域上创建多个逻辑接口，也就是“一（网络）对多
（逻辑接口）”的关系。每个
macvlan
逻辑接口都有自己的
MAC
地址
，只能够看到发送到
自己的
MAC
地址的流量。
（也就是说，
macvlan
接口无法嗅探其他
macvlan
接口的流量。）
