如图1所示HostA和HostC通过Switch双归属到SwitchA和SwitchB。为减轻SwitchA上数据流量的承载压力HostA以SwitchA为默认网关接入InternetSwitchB作为备份网关HostC以SwitchB为默认网关接入InternetSwitchA作为备份网关以实现流量的负载均衡。
说明
请确保该场景下互联接口的STP处于未使能状态。同时将互连接口退出VLAN1避免形成环路。因为在使能STP的环形网络中如果用交换机的VLANIF接口构建三层网络会导致某个端口被阻塞从而导致三层业务不能正常运行。 配置思路
采用VRRP负载分担实现流量的负载均衡配置思路如下
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。在SwitchA和SwitchB上创建VRRP备份组1和VRRP备份组2在备份组1中配置SwitchA为Master设备SwitchB为Backup设备在备份组2中配置SwitchB为Master设备SwitchA为Backup设备实现流量的负载均衡。
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

配置VRRP备份组
# 在SwitchA和SwitchB上创建VRRP备份组1配置SwitchA的优先级为120抢占延时为20秒作为Master设备SwitchB的优先级为缺省值作为Backup设备。

验证配置结果
# 完成上述配置后在SwitchA上执行display vrrp命令可以看到SwitchA在备份组1中作为Master设备在备份组2中作为Backup设备。
