A部分：实验调试及验证
A.1部分： 连接拓扑图
A.2部分：实验基本需求
1. 将S1、S2配置在一个VTP域内，VTP域名itaa。
2. S1为VTP SERVER，S2为VTP CLIENT。
3. 使用路由器模拟PC。

A.4部分：调试和验证过程
1. 查看S2的VLAN信息:
S2#show vlan
VLAN Name Status Ports
---- -------------------------------- --------- -------------------------------
1 default active Fa0/1, Fa0/2, Fa0/5, Fa0/6
Fa0/7, Fa0/8, Fa0/9, Fa0/11

Fa0/16, Fa0/17, Fa0/18, Fa0/19

2. 查看S2的VTP信息：
S2#show vtp status
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 255
Number of existing VLANs : 7
VTP Operating Mode : Client
VTP Domain Name : itaa
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x57 0x81 0xFC 0x11 0x77 0x80 0xD2 0xB6
Configuration last modified by 0.0.0.0 at 3-1-93 00:01:10
3. SW1和SW2的VLAN信息已经同步了，下面查看路由器R1的路由表信息：
R1#show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
10.0.0.0/24 is subnetted, 1 subnets
C 10.1.1.0 is directly connected, FastEthernet0/1.10
20.0.0.0/24 is subnetted, 1 subnets
C 20.1.1.0 is directly connected, FastEthernet0/1.20
R3上面也有了2条路由，路由上面也没有问题。
4. 下面开始测试:
PC01#ping 20.1.1.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 20.1.1.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 11/31/76 ms
B部分：实验结论
B.1部分：实验结论
1. VLAN之间的通信是实现3层上的通信。.
