浮动静态路由

拓扑图

如图，使一条静态路由成为两条负载均衡的RIP路由的浮动静态路由(也可以说成备份的路由)

给路由器设置地址

router 1的配置

Router>en
Router#conf t
Router(config)#int l0
Router(config-if)#ip addr 20.1.1.1 255.255.255.0
Router(config-if)#no shu
Router(config-if)#exit
Router(config)#int s0/3/0
Router(config-if)#ip addr 192.168.1.2 255.255.255.0
Router(config-if)#no shu
Router(config-if)#exit
Router(config)#int s0/3/1
Router(config-if)#clock rate 64000
Router(config-if)#ip addr 192.168.2.2 255.255.255.0
Router(config-if)#no shu
Router(config)#int f0/0
Router(config-if)#ip addr 192.168.10.2 255.255.255.0
Router(config-if)#no shu

router 2的配置

Router>en
Router#conf t
Router(config)#
Router(config)#int l0
Router(config-if)#ip addr 10.1.1.1 255.255.255.0
Router(config-if)#no shu
Router(config)#int s0/3/0
Router(config-if)#clock rate 64000
Router(config-if)#ip addr 192.168.1.1 255.255.255.0
Router(config-if)#no shu
Router(config-if)#exit
Router(config)#int s0/3/1
Router(config-if)#ip addr 192.168.2.1 255.255.255.0
Router(config-if)#no shu
Router(config)#int f0/0
Router(config-if)#ip addr 192.168.10.1 255.255.255.0
Router(config-if)#no shu

配置负载均衡的RIP路由

router 1的配置

Router(config)#route rip
Router(config-router)#ver 2
Router(config-router)#no auto-summary
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.2.0
Router(config-router)#network 20.1.1.0
Router(config-router)#exit

router 2的配置

Router(config)#
Router(config)#route rip
Router(config-router)#ver 2
Router(config-router)#no auto-summary
Router(config-router)#network 192.168.1.0
Router(config-router)#network 192.168.2.0
Router(config-router)#network 20.1.1.0
Router(config-router)#exit

查看路由表

查看router 1的路由表

Router#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
       i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
       * - candidate default, U - per-user static route, o - ODR
       P - periodic downloaded static route

配置浮动静态路由

router 1 的配置

Router(config)#ip route 10.1.1.0 255.255.255.0 192.168.10.1 121

router 2 的配置

Router(config)#ip route 20.1.1.0 255.255.255.0 192.168.10.2 121

查看router 1的路由表

Gateway of last resort is not set

断开RIP路由，在查看路由表
