【摘要】 多生成树绑定VRRP冗余协议在运营商网络中经常用到，这里模拟真实的网络环境做的实验。

一、组网需求

1、SW-A、SW-B选用两台锐捷的s5750 ；SW-C 、shwich d 选

用锐捷的 SW-C750和SW-C760

2、全网共有两个业务vlan ,为 vlan 10 、vlan 20

3、SW-A 、SW-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、SW-A、SW-B、SW-C、SW-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SW-A为根桥； vlan 20业务以SW-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、组网拓扑
