华为交换机VRRP配置

.3-128配置VRRP主备备份组网图配置思路采用VRRP主备备份实现网关冗余备份，配置思路如下：精品文档放心下载配置各设备接口IP地址及路由协议，使各设备间网络层连通。精品文档放心下载在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。精品文档放心下载操作步骤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。感谢阅读<HUAWEI>system-view[HUAWEI]sysnameSwitchA[SwitchA]vlanbatch100300精品文档放心下载.[SwitchA]interfacegigabitethernet1/0/1谢谢阅读[SwitchA-GigabitEthernet1/0/1]portlink-typehybrid谢谢阅读[SwitchA-GigabitEthernet1/0/1]porthybridpvidvlan300感谢阅读[SwitchA-GigabitEthernet1/0/1]porthybriduntaggedvlan300谢谢阅读[SwitchA-GigabitEthernet1/0/1]quit精品文档放心下载[SwitchA]interfacegigabitethernet1/0/2精品文档放心下载[SwitchA-GigabitEthernet1/0/2]portlink-typehybrid感谢阅读[SwitchA-GigabitEthernet1/0/2]porthybridpvidvlan100感谢阅读[SwitchA-GigabitEthernet1/0/2]porthybriduntaggedvlan100精品文档放心下载[SwitchA-GigabitEthernet1/0/2]quit感谢阅读[SwitchA]interfacevlanif100精品文档放心下载[SwitchA-Vlanif100]ipaddress10.1.1.124谢谢阅读[SwitchA-Vlanif100]quit[SwitchA]interfacevlanif300谢谢阅读[SwitchA-Vlanif300]ipaddress192.168.1.124谢谢阅读[SwitchA-Vlanif300]quit#配置Switch的二层转发功能。<HUAWEI>system-view[HUAWEI]sysnameSwitch[Switch]vlan100[Switch-vlan100]quit[Switch]interfacegigabitethernet1/0/1精品文档放心下载.[Switch-GigabitEthernet1/0/1]portlink-typehybrid精品文档放心下载[Switch-GigabitEthernet1/0/1]porthybridpvidvlan100感谢阅读[Switch-GigabitEthernet1/0/1]porthybriduntaggedvlan100谢谢阅读[Switch-GigabitEthernet1/0/1]quit精品文档放心下载[Switch]interfacegigabitethernet1/0/2谢谢阅读[Switch-GigabitEthernet1/0/2]portlink-typehybrid谢谢阅读[Switch-GigabitEthernet1/0/2]porthybridpvidvlan100感谢阅读[Switch-GigabitEthernet1/0/2]porthybriduntaggedvlan100精品文档放心下载[Switch-GigabitEthernet1/0/2]quit感谢阅读#配置SwitchA、SwitchB和SwitchC间采用OSPF协议进行互连。以SwitchA为谢谢阅读例，SwitchB和SwitchC的配置与SwitchA类似，详见配置文件。精品文档放心下载[SwitchA]ospf1[SwitchA-ospf-1]area0[SwitchA-ospf-1-area-0.0.0.0]network10.1.1.00.0.0.255感谢阅读[SwitchA-ospf-1-area-0.0.0.0]network192.168.1.00.0.0.255精品文档放心下载[SwitchA-ospf-1-area-0.0.0.0]quit谢谢阅读[SwitchA-ospf-1]quit配置VRRP备份组#在SwitchA上创建VRRP备份组1，配置SwitchA在该备份组中的优先级为120，并配置抢占时间为20秒。精品文档放心下载[SwitchA]interfacevlanif100精品文档放心下载[SwitchA-Vlanif100]vrrpvrid1virtual-ip10.1.1.111感谢阅读.[SwitchA-Vlanif100]vrrpvrid1priority120
