2、启动RIP

AR1

[r1]rip 1
[r1-rip-1]v 2
[r1-rip-1]network 192.168.1.0
[r1-rip-1]network 172.16.0.0
[r1-rip-1]network 1.0.0.0

AR2

[r2]rip
[r2-rip-1]v 2
[r2-rip-1]network 192.168.1.0
[r2-rip-1]network 2.0.0.0

AR3

[r3]rip
[r3-rip-1]v 2
[r3-rip-1]network 192.168.1.0
[r3-rip-1]network 3.0.0.0

AR4

[r4]rip
[r4-rip-1]v 2
[r4-rip-1]network 192.168.1.0
[r4-rip-1]network 4.0.0.0

AR5

[isp]rip
[isp-rip-1]v 2
[isp-rip-1]network 192.168.1.0

AR6

[r6]rip
[r6-rip-1]v 1
[r6-rip-1]network 192.168.1.0
[r6-rip-1]network 6.0.0.0

AR7

[r7]rip
[r7-rip-1]v 1
[r7-rip-1]network 192.168.1.0
[r7-rip-1]network 7.0.0.0

3、AR5缺省和AR6的互通

AR5

[isp-rip-1]default-route originate

AR6

[r6-GigabitEthernet0/0/0]rip version 2

4、AR1环回汇总和空接口

AR1

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]rip summary-address 172.16.0.0 255.255.252.0
[r1-GigabitEthernet0/0/1]rip summary-address 172.16.0.0 255.255.252.0
[r1]ip route-static 172.16.0.0 22 NULL 0

5、R3抓取流量并修改开销值

AR3

[r3]acl 2000
[r3-acl-basic-2000]rule permit source 172.16.0.0 0
[r3-acl-basic-2000]rule permit source 1.1.1.0 0
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]rip metricin 2000 10

6、R1和R2手工认证

AR1

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]rip authentication-mode simple cipher 123456

AR2

[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]rip authentication-mode simple cipher 123456

7、R6、R7路由器不能学习到达R1环回路由配置

[r6]acl 2000
[r6-acl-basic-2000]rule deny source 172.16.0.0 0
[r6-acl-basic-2000]rule deny source 1.1.1.0 0
[r6-acl-basic-2000]rule permit source any
[r6-rip-1]filter-policy 2000 import

8、R7上开启 telnet 及R2上nat 映射

AR7

[r7]aaa
[r7-aaa]local-user xujialong privilege level 15 password cipher 123456
[r7-aaa]local-user xujialong service-type telnet
[r7]user-interface vty 0 4
[r7-ui-vty0-4]authentication-mode aaa

AR2

[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]nat server protocol tcp global interface loopback 0 23
inside 7.7.7.7 23
Are you sure to continue?[Y/N]:y

9、对R2和R4上将数据包的传输方向进行策略改变

AR2

[r2]acl 2000
[r2-acl-basic-2000]rule permit source 7.0.0.0 0
[r2]int g 0/0/0
[r2-GigabitEthernet0/0/0]rip metricin 2000 10

AR4
[r4]acl 2000
[r4-acl-basic-2000]rule permit source 192.168.1.0 0
[r4]int g 0/0/1
[r4-GigabitEthernet0/0/1]rip metricin 2000 10
