2.使用SVI實現(xiàn)VLAN間的通信(圖)
環(huán)境:一臺三層交換機,兩臺pc機
三層交換機的配置:
Switch》enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
創(chuàng)建vlan 10 20
Switch(config)#vlan 10
Switch(config-vlan)#vlan 20
Switch(config-vlan)#exit
配置SVI接口ip
Switch(config)#interface vlan 10
%LINK-5-CHANGED: Interface Vlan10, changed state to up
Switch(config-if)#ip address 192.168.10.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#interface vlan 20
%LINK-5-CHANGED: Interface Vlan20, changed state to up
Switch(config-if)#ip address 192.168.20.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
改變接口模式并加入vlan
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up
Switch(config-if)#interface fastEthernet 0/2
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan20, changed state to up
Switch(config-if)#
看三層交換機的路由表:
Switch#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 192.168.10.0/24 is directly connected, Vlan10
C 192.168.20.0/24 is directly connected, Vlan20
Switch#
兩主機的配置與單臂路由中兩主機的配置一樣
3.跨交換機實現(xiàn)VLAN間的通信(圖)
環(huán)境:一臺三層交換機,兩臺二層交換機,兩臺pc機
三層交換機的配置(SW3)
Switch》enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
創(chuàng)建vlan 10 、 20 并設置ip
Switch(config)#vlan 10
Switch(config-vlan)#vlan 20
Switch(config-vlan)#exit
Switch(config)#interface vlan 10
%LINK-5-CHANGED: Interface Vlan10, changed state to up
Switch(config-if)#ip address 192.168.10.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#interface vlan 20
%LINK-5-CHANGED: Interface Vlan20, changed state to up
Switch(config-if)#ip address 192.168.20.1 255.255.255.0
Switch(config-if)#no shutdown
Switch(config-if)#exit
設置接口模式并加入相應的vlan(注意trunk口的設置)
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode trunk
Switch(config-if)#interface fastEthernet 0/1
Switch(config-if)#switchport access vlan 10
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan10, changed state to up
Switch(config)#interface fastEthernet 0/2
Switch(config-if)#switchport mode trunk
Switch(config-if)#interface fastEthernet 0/2
Switch(config-if)#switchport access vlan 20
%LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan20, changed state to up
Switch#
看路由表
Switch#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 192.168.10.0/24 is directly connected, Vlan10
C 192.168.20.0/24 is directly connected, Vlan20
SW21的配置
Switch》enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#vlan 10
Switch(config-vlan)#exit
Switch(config)#interface fastEthernet 0/1
Switch(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/1, changed state to up
Switch(config-if)#interface fastEthernet 1/1
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 10
Switch(config-if)#exit
Switch(config)#
SW22的配置

Switch》en
Switch#
Switch#configure ter
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#inter fas 1/1
Switch(config-if)#switchport mode trunk
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/1, changed state to down
%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/1, changed state to up
Switch(config-if)#switchport mode access
Switch(config-if)#inter fas 2/1
Switch(config-if)#switchport mode trunk

Switch(config-if)#exit
Switch(config)#vlan 20
Switch(config-vlan)#inter fas 1/1
Switch(config-if)#switchport access vlan 20
Switch(config-if)#
注意:兩交換機之間的鏈接是trunk鏈路
4.以上配置在模擬器上都可實現(xiàn)
在模擬器上配置其中pc圖片
上述三種方式pc機的配置都一樣
