实验环境:
实验目的:(两间公司之间的VLAN互通)
1、在B公司里配置三层交换机,把FA0/1 FA0/2 FA0/3 设置为TRUNK端口。
2、在B公司的三层交换机,创建VTP,并且创建VLAN20 VLAN30 VLAN40 VLAN100,并设置相应的IP地址。
3、在B公司的三层交换机,创建各VLAN的IP地址池。
4、在B公司的二层交换机,设置VTP CLIENT。
5、在B公司里,按图把各个PC加入到相应的VLAN口中,并查看是否可以获取IP地址。
6、在B公司的三层交换机里启用路由功能IP ROUTING,并测试公司内部各网段是否互通。
备注:以上步骤A公司的操作省略。
7、在两间公司的专线端口上关闭交换功能,并设置相应的IP地址。
8、先测试两公司之间的VLAN是否可互通。
9、因各VLAN不是直连,所以必须要在各公司的三层交换机添加相应的路由协议。
10、测试两个网段之间的PC是否可以互通。
实验步骤:
1、在B公司里配置三层交换机,把FA0/1 FA0/2 FA0/3 设置为TRUNK端口。

5、在B公司里,按图把各个PC加入到相应的VLAN口中,并查看是否可以获取IP地址。(其它交换机操作省略)
Switch#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#int fa0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
6、在B公司的三层交换机里启用路由功能IP ROUTING,并测试公司内部各网段是否互通。
在没有IP ROUTING的情况下如下:
在三层交换机启用IP ROUTING后,如下:
7、在两间公司的专线端口上关闭交换功能,并设置相应的IP地址和测试是否能PING通。
A公司:
CoreSW(config)#int fa0/4
CoreSW(config-if)#no switchport
CoreSW(config-if)#ip add 192.168.100.1 255.255.255.0
B公司:
CoreSWB(config)#int fa0/5
CoreSWB(config-if)#no switchport
CoreSWB(config-if)#ip add 192.168.100.2 255.255.255.0
两公司之间互通:
CoreSW#PING 192.168.100.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.100.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms
8、先测试两公司之间的VLAN是否可互通。
CoreSW#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
C 192.168.2.0/24 is directly connected, Vlan2
C 192.168.3.0/24 is directly connected, Vlan3
C 192.168.4.0/24 is directly connected, Vlan4
C 192.168.100.0/24 is directly connected, FastEthernet0/4
9、因各VLAN不是直连,所以必须要在各公司的三层交换机添加相应的路由协议。
A公司添加B公司的VLAN网段信息如下:
CoreSW#conf t
Enter configuration commands, one per line. End with CNTL/Z.
CoreSW(config)#router rip
CoreSW(config-router)#ver 2
CoreSW(config-router)#no au
CoreSW(config-router)#net 192.168.2.0
CoreSW(config-router)#net 192.168.3.0
CoreSW(config-router)#net 192.168.4.0
CoreSW(config-router)#net 192.168.100.0
B公司添加A公司的VLAN网段信息如下:
CoreSWB#conf t
Enter configuration commands, one per line. End with CNTL/Z.
CoreSWB(config)#router rip
CoreSWB(config-router)#ver 2
CoreSWB(config-router)#no au
CoreSWB(config-router)#net 192.168.20.0
CoreSWB(config-router)#net 192.168.30.0
CoreSWB(config-router)#net 192.168.40.0
CoreSWB(config-router)#net 192.168.100.0
RIP协议是把自己本网段的VLAN宣告到别的交换机上。
A公司三层交换机的路由表情况:
CoreSW#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

10、测试两个网段之间的PC是否可以互通。
