1、.word.图图 3-1283-128 配置 VRRP 主备备份组网图配置思路配置思路采用 VRRP 主备备份实现网关冗余备份，配置思路如下：1.配置各设备接口 IP 地址及路由协议，使各设备间网络层连通。2.在 SwitchA 和 SwitchB 上配置 VRRP 备份组。其中，SwitchA 上配置较高优先级和 20秒抢占延时，作为 Master 设备承当流量转发；SwitchB 上配置较低优先级，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
