3、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设备承担流量转发；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。<HUAWEI> system-viewHUAWEI sysname SwitchASwitchA vlan batch 100 300SwitchA interface

7、uit# 配置 SwitchA、SwitchB 和SwitchC间采用OSPF协议进行互连。以 SwitchA为例,SwitchB和SwitchC的配置与SwitchA类似，详见配置文件。SwitchA ospf 1SwitchA-ospf-1 area 0SwitchA-ospf-1-area-0.0.0,0network 10.1.1.0 0.0.0,255SwitchA-ospf-1-area-0.0.0,0network 192.168.1.0 0.0.0.255SwitchA-ospf-1-area-0.0.0,0quitSwitchA-ospf-1 quit2.配置VRRP备份组#

8、在SwitchA上创建VRRP备份组1,配置SwitchA在该备份组中白勺优先级为120,并配置抢占时间为20秒。SwitchA interface vlanif 100SwitchA-Vlanif100 vrrp vrid 1 virtual-ip 10.1.1,111SwitchA-Vlanif100 vrrp vrid 1 priority 120/ 设备在 VRRP 备份组中的优先级缺省为100 ,修改Master设备的优先级大于Backup设备SwitchA-Vlanif100 vrrp vrid 1 preempt-mode timer delay 20/设备在 VRRP 备份组中

9、缺省采用立即抢占方式。修改Master设备的延迟抢占时间，以避免在网络环境不稳定时，由于双方频繁抢占而导致流量中断的问题SwitchA-Vlanif100 quit#在SwitchB上创建VRRP备份组1,其在该备份组中的优先级采用缺省值100 （不需要配置）。SwitchB interface vlanif 100SwitchB-Vlanif100 vrrp vrid 1 virtual-ip 10.1.1.111SwitchB-Vlanif100 quit3.验证配置结果#完成上述配置以后，在 SwitchA和SwitchB上分别执行display vrrp 命令，可以看到 SwitchA
