在V1区域的所有接口上加上rip version 2
在R3的g0/0/1的入方向上设置偏移列表
[r3]interface g0/0/1
[r3-GigabitEthernet0/0/1]rip metricin 2000 4
首先在R7上做aaa认证,server-type为telnet,其次在R2边界路由器上做端口映射
[r7]aaa
[r7-aaa]local-user huazi privilege level 15 password cipher 123456
[r7-aaa]local-user huazi service-type telnet
[r7-aaa]q
[r7]user-interface vty 0 4
[r7-ui-vty0-4]authentication-mode aaa
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]nat static protocol tcp global current-interface 23 ins
