網段彙總：
AR1：
[r1]int g0/0/0

[r1-GigabitEthernet0/0/1]rip summary-address 172.16.0.0 255.255.252.0
R3使用R2通路R1環回：
[r3]acl 2000
[r3-acl-basic-2000]rule permit source 172.16.0.0 0.0.255.255
[r3-acl-basic-2000]rule permit source 1.1.1.0 0
[r3-acl-basic-2000]q
[r3-GigabitEthernet0/0/1]rip metricin 2000 10
[r3-GigabitEthernet0/0/1]display ip routing-table protocol rip
認證：
AR1：
[r1-GigabitEthernet0/0/0]rip authentication-mode md5 usual cipher 123456
AR2：
[r2-GigabitEthernet0/0/0]rip authentication-mode md5 usual cipher 123456 實作AR4為預設源：
[r4]ip route-static 0.0.0.0 0 45.0.0.2
[r4-rip-1]default-route originate
全網可達：
[r6]int g 0/0/0
[r6-GigabitEthernet0/0/0]ri
[r6-GigabitEthernet0/0/0]rip version 2
[r6-GigabitEthernet0/0/0]q

遠端登陸：
AR7開啟遠端登陸：
[r7]aaa
[r7-aaa]local-user admin privilege level 15 password cipher 123456
[r7-aaa]local-user admin service-type telnet
[r7-aaa]q
[r7]user-interface vty 0 4
[r7-ui-vty0-4]authentication-mode aaa
[r7-ui-vty0-4]q
AR6嘗試登陸：
<r6>telnet 7.7.7.7
Press CTRL_] to quit telnet mode
Trying 7.7.7.7 ...
Connected to 7.7.7.7 ...
Login authentication

<r7>
AR2做端口映射：
[r2]int g0/0/0
[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
