第一章 虚拟局域网(VLAN)路由

一、虚拟局域网(VLAN)

当前在我们构造企业网络时所采用的主干网络技术一般都是基于交换和虚拟网络的。交换技术将共享介质改为独占介质,大大提高网络速度。虚拟网络技术打破了地理环境的制约,在不改动网络物理连接的情况下可以任意将工作站在工作组或子网之间移动,工作站组成逻辑工作组或虚拟子网,提高信息系统的运作性能,均衡网络数据流量,合理利用硬件及信息资源。同时,利用虚拟网络技术,大大减轻了网络管理和维护工作的负担,降低网络维护费用。随着虚拟网络技术的应用,随之必然产生了在虚拟网间如何通讯的问题.

二、交换机间链路(ISL)协议

ISL(Interior Switching Link)协议用于实现交换机间的VLAN中继。它是一个信息包标记协议,在支持ISL接口上发送的帧由一个标准以太网帧及相关的VLAN信息组成。如下图所示,在支持ISL的接口上可以传送来自不同VLAN的数据。

三、虚拟局域网(VLAN)路由实例

3.1. 例一:

clip_image005

设备选用Catalyst5500交换机1台,安装WS-X5530-E3管理引擎,多块WS-X5225R及WS-X5302路由交换模块,WS-X5302被直接插入交换机,通过二个通道与系统背板上的VLAN 相连,从用户角度看认为它是1个1接口的模块,此接口支持ISL。在交换机内划有3个虚拟网,分别名为default、qbw、rgw,通过WS-X5302实现虚拟网间路由。

以下加重下横线部分,如set system name 5500C为需设置的命令。

设置如下:
