实验拓扑如下：在这里插入图片描述实验内容： 1.R4访问100.0.0.1 只可以通过左边的路由去访问 2. R4访问200.0.0.1 只可以通过右边的路由去访问

【1】接口IP地址的配置 R1

[R1]int g0/0/0 [R1-GigabitEthernet0/0/0]ip add 192.168.12.2 24 [R1-GigabitEthernet0/0/0]undo shut [R1-GigabitEthernet0/0/0]quit [R1]int g0/0/1 [R1-GigabitEthernet0/0/1]ip add 192.168.13.2 24 [R1-GigabitEthernet0/0/1]undo shut [R1-GigabitEthernet0/0/1]quit [R1]int LoopBack 0 [R1-LoopBack0]ip add 100.0.0.1 24 [R1-LoopBack0]quit [R1]int LoopBack 1 [R1-LoopBack1]ip add 200.0.0.1 24 [R1-LoopBack1]quit

[R2]int g0/0/0 [R2-GigabitEthernet0/0/0]ip add 192.168.12.1 24 [R2-GigabitEthernet0/0/0]undo shut [R2-GigabitEthernet0/0/0]quit [R2]int g0/0/1 [R2-GigabitEthernet0/0/1]ip add 192.168.24.2 24 [R2-GigabitEthernet0/0/1]undo shut [R2-GigabitEthernet0/0/1]quit

[R3]int g0/0/0 [R3-GigabitEthernet0/0/0]ip add 192.168.34.2 24 [R3-GigabitEthernet0/0/0]undo shut [R3-GigabitEthernet0/0/0]quit [R3]int g0/0/1 [R3-GigabitEthernet0/0/1]ip add 192.168.13.1 24 [R3-GigabitEthernet0/0/1]undo shut [R3-GigabitEthernet0/0/1]quit

[R4]int g0/0/0 [R4-GigabitEthernet0/0/0]ip add 192.168.34.1 24 [R4-GigabitEthernet0/0/0]undo shut [R4-GigabitEthernet0/0/0]int g0/0/1 [R4-GigabitEthernet0/0/1]ip add 192.168.24.1 24 [R4-GigabitEthernet0/0/1]undo shut [R4-GigabitEthernet0/0/1]quit

【2】rip的配置 R1

[R1]rip [R1-rip-1]version 2 [R1-rip-1]undo summary //关闭自动汇总 [R1-rip-1]net 100.0.0.0 [R1-rip-1]net 200.0.0.0 [R1-rip-1]net 192.168.12.0 [R1-rip-1]net 192.168.13.0

[R2]rip [R2-rip-1]vers [R2-rip-1]version 2 [R2-rip-1]undo su [R2-rip-1]undo summary [R2-rip-1]net 192.168.12.0 [R2-rip-1]net 192.168.24.0 [R2-rip-1]net 100.0.0.0 [R2-rip-1]net 200.0.0.0

[R3]rip [R3-rip-1]vers [R3-rip-1]version 2 [R3-rip-1]undo su [R3-rip-1]undo summary [R3-rip-1]net 192.168.13.0 [R3-rip-1]net 192.168.34.0 [R3-rip-1]net 100.0.0.0 [R3-rip-1]net 200.0.0.0

[R4]rip [R4-rip-1]vers [R4-rip-1]version 2 [R4-rip-1]undo su [R4-rip-1]undo summary [R4-rip-1]net 192.168.24.0 [R4-rip-1]net 192.168.34.0

【3】查看R4的路由表：会发现去100.0.0.0网段有两条等值路由；去200.0.0.0网段有两条等值路由。在这里插入图片描述

【4】路由策略过滤路由前缀地址列表： ip ip-prefix ip-prefix-name index index-number permit/deny ip-address(指定地址) mask-leght【匹配的结果是所有ip-address/mask-leght范围的地址都可以通过过滤】过滤策略：filter-policy ip-prefix ip-prefix-name gateway ip-prefix-name import interface【ip-prefix ip-prefix-name：接收路由过滤；gateway ip-prefix-name ：发布路由过滤的网关】 R4：

[R4]ip ip-prefix left index 10 permit 100.0.0.0 24 [R4]ip ip-prefix right index 10 permit 200.0.0.0 24 [R4]ip ip-prefix leftgateway index 10 permit 192.168.24.2 32 [R4]ip ip-prefix rightgateway index 10 permit 192.168.34.2 32 [R4]rip [R4-rip-1]filter-policy ip-prefix left gateway leftgateway import GigabitEthernet 0/0/1 [R4-rip-1]filter-policy ip-prefix right gateway rightgateway import GigabitEthernet 0/0/0

【5】查看 R4路由表发现访问100.0.0.0网段只能通过左边的路由去访问，访问200.0.0.0网段只能通过右边的路由去访问。在这里插入图片描述
