华为浮动静态路由及负载均衡

**浮动静态路由及负载均衡**概述浮动静态路由是通过配置去往同一网段但优先级不同的静态路由保证在网络中优先级较高的路由即主路由失效的情况下提供备份路由。备份路由一般不会出现在路由表中。只有主链路失效时浮动路由才会浮出来。实验拓扑实验要求网络互通采用静态路由实现PC1与PC2链路冗余负载均衡PC1与PC2之间通信时采用浮动静态路由实现。链路pc1-R2-R3-pc2为主链路另一条为备份链路。配置思路规划网段配置相应地址配置主链路静态路由配置浮动路由实现备份配置负载均衡基本配置R1system-view[Huawei]int e0/0/0[Huawei-Ethernet0/0/0]undo shutdown[Huawei-Ethernet0/0/0]ip add 10.1.1.2 24[Huawei-Ethernet0/0/0]quit[Huawei]int e0/0/1[Huawei-Ethernet0/0/1]undo shutdown[Huawei-Ethernet0/0/1]ip add 192.168.10.254 24[Huawei-Ethernet0/0/1]quit[Huawei]int g0/0/0[Huawei-GigabitEthernet0/0/0]undo shutdown[Huawei-GigabitEthernet0/0/0]ip add 10.3.3.1 24[Huawei-GigabitEthernet0/0/0]quit[Huawei]R2system-view[Huawei]int e0/0/0[Huawei-Ethernet0/0/0]undo shutdown[Huawei-Ethernet0/0/0]ip add 10.1.1.1 24[Huawei-Ethernet0/0/0]quit[Huawei]int e0/0/1[Huawei-Ethernet0/0/1]undo shutdown[Huawei-Ethernet0/0/1]ip add 10.2.2.1 24[Huawei-Ethernet0/0/1]quitR3system-view[Huawei]sysname R3[R3]int e0/0/0[R3-Ethernet0/0/0]undo shutdown[R3-Ethernet0/0/0]ip add 10.2.2.2 24[R3-Ethernet0/0/0]int e0/0/1[R3-Ethernet0/0/1]undo shutdown[R3-Ethernet0/0/1]ip add 192.168.20.254 24[R3-Ethernet0/0/1]int g0/0/0[R3-GigabitEthernet0/0/0]undo shutdown[R3-GigabitEthernet0/0/0]ip add 10.3.3.2 24[R3-GigabitEthernet0/0/0]quit配置主链路静态路由R1[Huawei]ip route-static 192.168.20.0 24 10.3.3.2R2[Huawei]ip route-static 192.168.10.0 24 10.1.1.2[Huawei]ip route-static 192.168.20.0 24 10.2.2.2R3[Huawei]iproute-static 192.168.10.0 24 10.3.3.1配置备份链路R1[R1]ip route-static 192.168.20.0 24 10.1.1.1 preference 100 //优先级默认为60R3[R3]ip route-static 192.168.20.0 24 10.2.2.1 preference 100在R1上查看静态路由的路由信息路由显示到目的地址pc2有两条优先级为60和100的静态路由.然后关闭路由器R1的接口g/0/0/0测试备份链路[R1]interface g0/0/0[R1-GigabitEthernet0/0/0]shutdown配置负载均衡R1[R1]interface g0/0/0[R1-GigabitEthernet0/0/0]undo shutdown[R1]ip route-static 192.168.20.0 255.255.255.0 10.1.11R3[R3]ip route-static 192.168.10.0 255.255.255.0 10.2.2.1查看R1路由表看到去往192.168.20.0网段有两条不同吓一跳的路由条目及实现负载均衡。
