Cisco Packet Tracer三層交換機使用路由協(xié)議實驗 的方法
實驗環(huán)境:
實驗?zāi)康模?兩間公司之間的VLAN互通)
1、在B公司里配置三層交換機,把FA0/1 FA0/2 FA0/3 設(shè)置為TRUNK端口。
2、在B公司的三層交換機,創(chuàng)建VTP,并且創(chuàng)建VLAN20 VLAN30 VLAN40 VLAN100,并設(shè)置相應(yīng)的IP地址。
3、在B公司的三層交換機,創(chuàng)建各VLAN的IP地址池。
4、在B公司的二層交換機,設(shè)置VTP CLIENT。
5、在B公司里,按圖把各個PC加入到相應(yīng)的VLAN口中,并查看是否可以獲取IP地址。
6、在B公司的三層交換機里啟用路由功能IP ROUTING,并測試公司內(nèi)部各網(wǎng)段是否互通。
備注:以上步驟A公司的操作省略。
7、在兩間公司的專線端口上關(guān)閉交換功能,并設(shè)置相應(yīng)的IP地址。
8、先測試兩公司之間的VLAN是否可互通。
9、因各VLAN不是直連,所以必須要在各公司的三層交換機添加相應(yīng)的路由協(xié)議。
10、測試兩個網(wǎng)段之間的PC是否可以互通。
實驗步驟:
1、在B公司里配置三層交換機,把FA0/1 FA0/2 FA0/3 設(shè)置為TRUNK端口。
CoreSWB(config)#int fa0/1
CoreSWB(config-if)#switchport trunk encapsulation dot1q
CoreSWB(config-if)#switchport mode trunk
CoreSWB(config)#int fa0/2
CoreSWB(config-if)#switchport trunk encapsulation dot1q
CoreSWB(config-if)#switchport mode trunk
CoreSWB(config)#int fa0/3
CoreSWB(config-if)#switchport trunk encapsulation dot1q
CoreSWB(config-if)#switchport mode trunk
2、在B公司的三層交換機,創(chuàng)建VTP,并且創(chuàng)建VLAN20 VLAN30 VLAN40 VLAN100,并設(shè)置相應(yīng)的IP地址。
CoreSWB(vlan)#vtp domain senya
Changing VTP domain name from NULL to senya
CoreSWB(vlan)#vtp server
Device mode already VTP SERVER.
CoreSWB#conf t
Enter configuration commands, one per line. End with CNTL/Z.
CoreSWB(config)#vlan 20
CoreSWB(config-vlan)#exit
CoreSWB(config)#vlan 30
CoreSWB(config-vlan)#exit
CoreSWB(config)#vlan 40
CoreSWB(config-vlan)#exit
CoreSWB(config)#vlan 100
CoreSWB(config-vlan)#exit
CoreSWB(config)#int vlan20
CoreSWB(config-if)#ip add 192.168.20.1 255.255.255.0
CoreSWB(config-if)#exit
CoreSWB(config)#int vlan30
CoreSWB(config-if)#ip add 192.168.30.1 255.255.255.0
CoreSWB(config-if)#exit
CoreSWB(config)#int vlan40
CoreSWB(config-if)#
%LINK-5-CHANGED: Interface Vlan40, changed state to up
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan40, changed state to up
CoreSWB(config-if)#ip add 192.168.40.1 255.255.255.0
CoreSWB(config-if)#exit
CoreSWB(config-if)#exit
3、在B公司的三層交換機,創(chuàng)建各VLAN的IP地址池。
CoreSWB(config)#ip dhcp pool vlan20
CoreSWB(dhcp-config)#network 192.168.20.0 255.255.255.0
CoreSWB(dhcp-config)#default-router 192.168.20.1
CoreSWB(dhcp-config)#exit
CoreSWB(config)#ip dhcp pool vlan30
CoreSWB(dhcp-config)#network 192.168.30.0 255.255.255.0
CoreSWB(dhcp-config)#default-router 192.168.30.1
CoreSWB(dhcp-config)#exit
CoreSWB(config)#ip dhcp pool vlan40
CoreSWB(dhcp-config)#network 192.168.40.0 255.255.255.0
CoreSWB(dhcp-config)#default-router 192.168.40.1
CoreSWB(dhcp-config)#exit
4、在B公司的二層交換機,設(shè)置VTP CLIENT。(只顯示一個交換機的操作步驟)
Switch#vlan database
% Warning: It is recommended to configure VLAN from config mode,
as VLAN database mode is being deprecated. Please consult user
documentation for configuring VTP/VLAN in config mode.
Switch(vlan)#vtp domain senya
Domain name already set to senya.
Switch(vlan)#vtp client
Setting device to VTP CLIENT mode.
Switch(vlan)#exit

Switch#show vlan

5、在B公司里,按圖把各個PC加入到相應(yīng)的VLAN口中,并查看是否可以獲取IP地址。(其它交換機操作省略)
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公司的三層交換機里啟用路由功能IP ROUTING,并測試公司內(nèi)部各網(wǎng)段是否互通。
在沒有IP ROUTING的情況下如下:
在三層交換機啟用IP ROUTING后,如下:
7、在兩間公司的專線端口上關(guān)閉交換功能,并設(shè)置相應(yīng)的IP地址和測試是否能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
兩公司之間互通:
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、先測試兩公司之間的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不是直連,所以必須要在各公司的三層交換機添加相應(yīng)的路由協(xié)議。
A公司添加B公司的VLAN網(wǎng)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網(wǎng)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協(xié)議是把自己本網(wǎng)段的VLAN宣告到別的交換機上。
A公司三層交換機的路由表情況:
CoreSW#show ip route
