7、l TIANXUAN refCount 2pool TIANXUAN: netmask 255.255.255.0 start 202.96.1.3 end 202.96.1.100 type generic, total addresses 98 , allocated 2 （2%）, misses 0R1#show ip nat translationsPro Inside global Inside local Outside local Outside global- 202.96.1.3 192.168.1.1 - - 202.96.1.4 192.168.1.2 202.96.1.

8、5 192.168.1.3 202.96.1.6 192.168.1.4R1#debug ip natIP NAT debugging is onR1#NAT: s=192.168.1.1-202.96.1.6, d=2.2.2.25NAT*: s=2.2.2.2, d=202.96.1.6-192.168.1.15二、R2配置：Router（config）#hostname R2R2（config）#R2（config）#endR2#copy running-config startup-configR2（config）#interface serial 3/0R2（config-if）#i

9、p address 202.96.1.2 255.255.255.0R2（config-if）#no shutdownR2（config）#interface loopback 0R2（config-if）#ip address 2.2.2.2 255.255.255.0R2（config）#router ripR2（config-router）#version 2R2（config-router）#no auto-summaryR2（config-router）#network 2.0.0.0R2（config-router）#network 202.96.1.0R2#ping 2.2.2.

10、2Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:!Success rate is 100 percent （5/5）, round-trip min/avg/max = 16/16/16 msR2#ping 202.96.1.1Sending 5, 100-byte ICMP Echos to 202.96.1.1, timeout is 2 seconds:Success rate is 100 percent （5/5）, round-trip mi

11、n/avg/max = 31/31/32 msR2#ping 192.168.1.1Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:.Success rate is 0 percent （0/5）三、小结核心：动态地址池的IP地址应为合法地址，可能实际中不可能申请了这么多的IP地址。那就把内部本地IP映射到内部全局的一个合法IP上。R1（config）#ip nat pool TX 202.96.1.1 202.96.1.1 netmask 255.255.255.0R1（config）#ip nat in

12、side source list 1 pool TX overload /overload为参数,表示复用公用地址在打这个核心命令时,自己先参照书上先打ip nat pool TX .,之后很容易忘了在接口上申明,R1（config-if）#ip nat inside 做NAT时,心里首先就要想到接口申明.Trunk配置一、交换机SW1配置：Switch1（config）#vlan 20Switch1（config）#vlan 30Switch1（config）#interface fastEthernet 0/1Switch1（config-if）#switchport mode acces

13、sSwitch1（config-if）#switchport access vlan 20Switch1（config）#interface fastEthernet 0/2Switch1（config-if）#switchport access vlan 30Switch1#show vlanVLAN Name Status Ports- - - -1 default active Fa0/3, Fa0/4, Fa0/5, Fa0/6 Fa0/7, Fa0/8, Fa0/9, Fa0/10 Fa0/11, Fa0/12, Fa0/13, Fa0/14 Fa0/15, Fa0/16, Fa0/
