SwitchA和SwilchB上配置VRRP备份组。

3、其中.SwitchA 配置较髙优先级和20秒抢占延时，作为Master设备承担流量转发：SwitchB 配置较低优先级，作为备 用交换机，实现网关冗余备份.操作步骤1. 配置设备间的网络互连#配置设备各接口的IP地址，以SwitchA为例。SwitchB和SwitchC的配置与SwitchA 类似，详见配置文件。 system-viewHUAWEI sysname SwitchASwitchA vlan batch 100 3001/0/1SwitchA interface gigabitethernetSwitchA-GigabitEthernet1/0/2 portlink-type hy
