一、组网需求
1、witcha、witchb选用两台锐捷的5750;witchc、hwichd选
用锐捷的3750和3760
2、全网共有两个业务vlan,为vlan10、vlan203、Switcha、witchb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、Switcha、witchb、witchc、witchd都起用mtp多生成数协议,并且
所有设备都属于同一个mt域,且实例映射一致(vlan10映射实例1、vlan20映射实例2其他vlan映射默认实例0)。
5、Vlan10业务以witcha为根桥;vlan20业务以witchb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
