[R5]ip route-static 192.168.1.12 30 192.168.1.21
4、配置全网通
（1）配置缺省路由，实现到1.0.0.0/24互通。此时实现内网通
[R1]ip route-static 0.0.0.0 0 192.168.1.2
[R1]ip route-static 0.0.0.0 0 192.168.1.6
[R2]ip route-static 0.0.0.0 0 192.168.1.10
[R3]ip route-static 0.0.0.0 0 192.168.1.14
[R4]ip route-static 0.0.0.0 0 192.168.1.18
[R4]ip route-static 0.0.0.0 0 192.168.1.22
[R5]ip route-static 0.0.0.0 0 12.0.0.6
（2）在R5路由器上配置nat
[R5]acl 2000
[R5-acl-basic-2000]rule permit source 192.168.1.0 0.0.0.255
[R5-acl-basic-2000]int g0/0/1
[R5-GigabitEthernet0/0/1]nat outbound 2000
测试全网通
5、防环，做黑洞路由配置
[R1]ip route-static 192.168.1.32 27 NULL 0
[R2]ip route-static 192.168.1.64 27 NULL 0
[R4]ip route-static 192.168.1.128 27 NULL 0
6、备份
[R4]ip route-static 0.0.0.0 0 192.168.1.22 preference 61
[R5]ip route-static 192.168.1.0 255.255.255.252 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.4 255.255.255.252 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.8 255.255.255.252 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.12 255.255.255.252 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.32 255.255.255.224 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.64 255.255.255.224 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.96 255.255.255.224 192.168.1.21 preference 61
[R5]ip route-static 192.168.1.128 255.255.255.224 192.168.1.21 preference 61
测试是否可以通过100M/s
7、R6 telnet R5的公有地址时，实际登录到R1上；
[R1-aaa]local-user wangdaye password cipher wdy12345 privilege level 15
[R1-aaa]local-user wangdaye service-type telnet
[R1]user-interface vty 0 4
[R1-ui-vty0-4]authentication-mode aaa
[R5]int g0/0/1
[R5-GigabitEthernet0/0/1]nat server protocol tcp global current-interface 23 inside 192.168.1.1 23
