交换机_vrrp+mstp配置实例.doc

交换机_vrrp+mstp配置实例交换机 vrrp+mstp配置实例一、 组网需求1、 switch a 、switch b选用两台锐捷的s5750 ；switch c 、shwich d 选用锐捷的 s3750和s37602、 全网共有两个业务vlan ,为 vlan 10 、vlan 203、 switch a 、switch b 都分别对两vlan起用两vrrp组，实现两组的业务的负载分担和备份。4、 switch a、switch b、switch c、switch d 都起用 mstp多生成数协议，并且所有设备都属于同一个mst域，且实例映射一致（vlan 10映射实例1、vlan 20映射实例2 其他vlan映射默认实例0）。5、 Vlan 10业务以switch a为根桥； vlan 20业务以switch b为根桥；实现阻断网络环路，并能实现不同vlan数据流负载分担功能。二、 组网图三、 配置步骤Switch a配置：s1#show runBuilding configuration.Current configuration : 1651 bytes!version RGNOS 10.2.00(2), Release(29287)(Tue Dec 25 20:39:14 CST 2007
