一、实验拓扑
二、实验要求
1、按照图示配置 IP 地址,R1,R3,R4 上使用 loopback 口模拟业务网段
2、R1和R3运行RIPv2,R2,R3和R4运行OSPF,各自协议内部互通
3、在 RIP 和 oSPF 间配置双向路由引入,要求除 R4 上的业务网段以外,其他业务网段路由都引入到对方协议内部
4、使用路由过滤,使 R4 无法学习到 R1的业务网段路由,要求使用 prefix-list 进行匹配
5、0SPF 区域中不能出现 RIP 协议报文
三、实验步骤
1.网段划分如上图,对接口配置如下
对R1:
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ip add 100.1.1.1 24
[R1-GigabitEthernet0/0/0]int l0
[R1-LoopBack0]ip add 192.168.0.1 32
[R1-LoopBack0]int l1
[R1-LoopBack1]ip add 192.168.1.1 32
对R2:
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 100.1.1.2 24
[R2-GigabitEthernet0/0/0]int g0/0/1
[R2-GigabitEthernet0/0/1]ip add 100.2.2.2 24
对R3:
[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ip add 100.2.2.3 24
[R3-GigabitEthernet0/0/0]int g0/0/1
[R3-GigabitEthernet0/0/1]ip add 100.3.3.3 24
[R3-GigabitEthernet0/0/1]int l0
[R3-LoopBack0]ip add 192.168.2.1 32
[R3-LoopBack0]int l1
[R3-LoopBack1]ip add 192.168.3.1 32
对R4:
[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip add 100.3.3.4 24
[R4-GigabitEthernet0/0/0]int l0
[R4-LoopBack0]ip add 192.168.4.1 32
[R4-LoopBack0]int l1
[R4-LoopBack1]ip add 192.168.5.1 32
2.在R1和R3上配置RIPv2,在R2、R3和R4上配置OSPF
对R1:
[R1]rip 1
[R1-rip-1]v 2
[R1-rip-1]undo summary
[R1-rip-1]ne 100.0.0.0
[R1-rip-1]ne 192.168.0.0
[R1-rip-1]ne 192.168.1.0
对R2:
[R2]rip 1
[R2-rip-1]v 2
[R2-rip-1]undo summary
[R2-rip-1]ne 100.0.0.0
[R2-rip-1]ospf 1 rou
[R2-rip-1]q
[R2]ospf 1 router-id 1.1.1.1
[R2-ospf-1]a 0
[R2-ospf-1-area-0.0.0.0]ne 100.2.2.0 0.0.0.255
对R3:
[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]a 0
[R3-ospf-1-area-0.0.0.0]ne 100.2.2.0 0.0.0.255[R3-ospf-1-area-0.0.0.0]ne 192.168.3.1 0.0.0.0
[R3-ospf-1-area-0.0.0.0]q
[R3-ospf-1]a 1
[R3-ospf-1-area-0.0.0.1]ne 100.3.3.0 0.0.0.255
对R4:
[R4]ospf 1 router-id 4.4.4.4
[R4-ospf-1]a 1
[R4-ospf-1-area-0.0.0.1]ne 0.0.0.0 255.255.255.255
3.在R2上配置双向路由引入
对R2:
[R2]rip 1
[R2-rip-1]imp
[R2-rip-1]import-route ospf
[R2-rip-1]q
[R2]ospf 1
[R2-ospf-1]imp
[R2-ospf-1]import-route rip
查看:
R1
R4
4.在R2创建acl,过滤R4,允许其他通过
对R2:
[R2]acl 2000
[R2-acl-basic-2000]rule deny source 192.168.4.0 0.0.1.255
[R2-acl-basic-2000]rule permit source 0.0.0.0 255.255.255.255[R2-acl-basic-2000]q
[R2]route-policy xg permit node 10
[R2-route-policy]if-match acl 2000
[R2-route-policy]q
[R2]rip 1
[R2-rip-1]import-route ospf 1 rou
[R2-rip-1]import-route ospf 1 route-policy xg
查看
R1
5.在R4上创建prefix-list,拒绝192.168.0.0 23 地址范围的路由,允许其他
对R4:
[R4]ip ip-prefix aa index 10 deny 192.168.0.0 23 less-equal 32
[R4]ip ip-prefix aa index 20 permit 0.0.0.0 0 less-equal 32
