三层交换实现不同VLAN间的通信

实验内容:
三层交换机具有路由功能,在一般三层交换都是需要手动开启其路由功能。只是神州的5526S交换机不用开启,可以直接使用。具体思路就是,在SwitchA上设置VLAN10,且VLAN10的IP地址为PC1的网关,另一半同理。
(1)测试机配置
测试机PC1连接交换机A 1口,ip 192.168.10.1 网关:192.168.10.10
测试机PC2连接交换机B 10口,ip 192.168.20.1网关:192.168.20.10
(2)DCRS-5526S配置
SwitchA-Config[完整配置]
switch>enable
switch#config
switch(Config)#hostname SwitchA
SwitchA(Config)#interface ethernet 0/0/23
SwitchA(Config-Ethernet0/0/23)#switchport mode trunk
Set the port Ethernet0/0/23 mode TRUNK successfully
SwitchA(Config-Ethernet0/0/23)#exit
SwitchA(Config)#telnet-server enable
Telnetd already enabled.
SwitchA(Config)#telnet-user shenzhi password 0 123
SwitchA(Config)#ip http server
web server is on
SwitchA(Config)#web-user shenzhi password 0 123
SwitchA(Config)#vlan 10
SwitchA(Config-Vlan10)#switchport interface ethernet 0/0/1-8
Set the port Ethernet0/0/1 access vlan 10 successfully
Set the port Ethernet0/0/2 access vlan 10 successfully
Set the port Ethernet0/0/3 access vlan 10 successfully
Set the port Ethernet0/0/4 access vlan 10 successfully
Set the port Ethernet0/0/5 access vlan 10 successfully
Set the port Ethernet0/0/6 access vlan 10 successfully
Set the port Ethernet0/0/7 access vlan 10 successfully
Set the port Ethernet0/0/8 access vlan 10 successfully
SwitchA(Config-Vlan10)#interface vlan 10
SwitchA(Config-If-Vlan10)#ip address 192.168.10.10 255.255.255.0
SwitchA(Config-If-Vlan10)#vlan 20
SwitchA(Config-Vlan20)#interface vlan 20
SwitchB(Config-If-Vlan20)#ip address 192.168.20.10 255.255.255.0

SwitchB-Config[完整配置]
PC1<--->SwitchA(e0/0/1)
PC2<--->SwitchB(e0/0/10)
注意:PC2的网关并不是SwitchB上VLAN20的IP地址,而是SwitchA上的VLAN20的IP地址,并且在SwitchB上的VLAN20并未设置IP地址,因为意义不大。
switch>enable
switch#config
switch(Config)#hostname SwitchB
SwitchB(Config)#telnet-server enable
Telnetd already enabled.
SwitchB(Config)#telnet-user shenzhi password 0 123
SwitchB(Config)#ip http server
web server is on
SwitchB(Config)#web-user shenzhi password 0 123
SwitchB(Config)#interface ethernet 0/0/23
SwitchB(Config-Ethernet0/0/23)#switchport mode trunk
Set the port Ethernet0/0/23 mode TRUNK successfully
SwitchB(Config-Ethernet0/0/23)#vlan 20
SwitchB(Config)#interface ethernet 0/0/23
SwitchB(Config-Ethernet0/0/23)#switchport mode trunk
Set the port Ethernet0/0/23 mode TRUNK successfully
SwitchB(Config-Ethernet0/0/23)#vlan 20
SwitchB(Config-Vlan20)#switchport interface ethernet 0/0/10-15
Set the port Ethernet0/0/10 access vlan 20 successfully
Set the port Ethernet0/0/11 access vlan 20 successfully
Set the port Ethernet0/0/12 access vlan 20 successfully
Set the port Ethernet0/0/13 access vlan 20 successfully
Set the port Ethernet0/0/14 access vlan 20 successfully
Set the port Ethernet0/0/15 access vlan 20 successfully
(3)测试机A可以ping通测试机B。
实验要求:
掌握Vlan的定义,同一Vlan中的主机只要IP为同一网段便可以相互通信。
