[R7-LoopBack0]int g0/0/0
[R7-GigabitEthernet0/0/0]ip add 67.1.1.2 24
2、配置RIP的基本功能 :启动RIP进程,在指定网段使能RIP
R1
[R1]rip 100
[R1-rip-100]version 2
[R1-rip-100]network 1.0.0.0
[R1-rip-100]network 12.0.0.0
[R1-rip-100]network 14.0.0.0
R2
[R2]rip 100
[R2-rip-100]version 2
[R2-rip-100]network 12.0.0.0
[R2-rip-100]network 2.0.0.0
[R2-rip-100]network 23.0.0.0
R3
[R3]rip 100
[R3-rip-100]version 2
[R3-rip-100]network 23.0.0.0
[R3-rip-100]network 3.0.0.0
[R3-rip-100]network 34.0.0.0
R4
[R4]rip 100
[R4-rip-100]version 2
[R4-rip-100]network 14.0.0.0
[R4-rip-100]network 4.0.0.0
[R4-rip-100]network 34.0.0.0
[R4-rip-100]network 45.0.0.0
[R4-rip-100]network 46.0.0.0
R5
[R5]rip 100
[R5-rip-100]version 2
[R5-rip-100]network 5.0.0.0
[R5-rip-100]network 45.0.0.0
R6
[R6]rip 200
[R6-rip-200]version 1
[R6-rip-200]network 46.0.0.0
[R6-rip-200]network 6.0.0.0
[R6-rip-200]network 67.0.0.0
R7
[R7]rip 200
[R7-rip-200]version 1
[R7-rip-200]network 67.0.0.0
[R7-rip-200]network 7.0.0.0
3、R1创建环回 172.16.1.1/24 172.16.2.1/24 172.16.3.1/24
创建环回
[R1]int l 1
[R1-LoopBack1]ip add 172.16.1.1 24
[R1-LoopBack1]int l 2
[R1-LoopBack2]ip add 172.16.2.1 24
[R1-LoopBack2]int l 3
[R1-LoopBack3]ip add 172.16.3.1 24
指定这些网段使能RIP
[R1]rip 100
[R1-rip-100]network 172.16.0.0
4、R3使用R2访问R1环回
减少路由条目数量,汇总R1的环回接口
[R1] int g 0/0/0
[R1-GigabitEthernet0/0/0] rip summary-address 172.16.0.0 255.255.252.0
[R1] int g 0/0/1
[R1-GigabitEthernet0/0/1] rip summary-address 172.16.0.0 255.255.252.0
修改R3接口G 0/0/0的附加度量值,控制RIP的路由选路,不让从R1环回来的路由经过R4
[R3] acl 2000
[R3-acl-basic-2000] rule permit source 1.1.1.0 0
[R3-acl-basic-2000] rule permit source 172.16.0.0 0
[R3] int g 0/0/0
[R3-GigabitEthernet0/0/0] rip metricin 2000 2
5、R5创建一个环回模拟运营商,不能通告,但保证全网可达,需配置缺省路由
[R5] int l 1
[R5-LoopBack1] ip add 55.5.5.5 32
[R5] rip 100
[R5-rip-100] default-route originate
在R6的g 0/0/0接口配合RIP V2版本,保证路由互通
[R6]int g 0/0/0
[R6-GigabitEthernet0/0/0]rip version 2
在R7上做telnet,此时R7可以被telnet
[R7]user-interface vty 0 4
[R7-ui-vty0-4]set authentication password cipher huawei
6、 R1 telnet R2环回实际telnet 到R7上
R1到R7
[R2]int g 0/0/0
[R2-GigabitEthernet0/0/0]nat server protocol tcp global interface loopback 0 23
inside 7.7.7.7 23
Warning:The port 23 is well-known port. If you continue it may cause function fa
ilure.
Are you sure to continue?[Y/N]:y
R7到R1
[R2]acl 2000
[R2-acl-basic-2000]rule permit source 7.0.0.0 0
[R2-acl-basic-2000]int g 0/0/0
[R2-GigabitEthernet0/0/0]rip metricin 2000 2
[R4]acl 2000
[R4-acl-basic-2000]rule permit source 12.1.1.0 0
[R4-acl-basic-2000]int g 0/0/0
[R4-GigabitEthernet0/0/0]rip metricin 2000 3
7、R6-R7路由器不能学习到达R1环回路由
[R6]acl 2000
[R6-acl-basic-2000]rule deny source 1.1.1.0 0
[R6-acl-basic-2000]rule deny source 172.16.0.0 0
[R6-acl-basic-2000]rule permit source any
[R6]rip 200
[R6-rip-200]filter-policy 2000 import GigabitEthernet 0/0/0
