ensp中路由器如何配置vlan(关于cisco路由器vlan配置问题~)

小编:小丢 更新时间:2022-10-27

一、ensp中路由器如何配置vlan

创建vlan:

[sw1]vlan 10 //创建VLAN10

[sw1-vlan10]vlan 20 //创建VLAN20

配置access:

[sw1]interface Ethernet 0/0/1 //进入以太网接口0/0/1

[sw1-Ethernet0/0/1]port link-type access //配置接口类型为Access

[sw1-Ethernet0/0/1]port default vlan 10 //分配接口给VLAN10

配置trunk:

[sw1]interface Ethernet 0/0/4

[sw1-Ethernet0/0/4]port link-type trunk //配置接口类型为trunk

[sw1-Ethernet0/0/4]port trunk allow-pass vlan 10 20//trunk口允许通过的VLAN


二、关于cisco路由器vlan配置问题~

需要通过单臂路由才能是不同的vlan之间通信,具体配置就是进入子接口中封装802.1Q协议配置vlan的IP地址并且no shutdown

Router(config)#interface f0/0.1

%LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.1, changed state to upRouter(config-subif)#en

Router(config-subif)#encapsulation do

Router(config-subif)#encapsulation dot1Q ?

<1-1005> IEEE 802.1Q VLAN ID

Router(config-subif)#encapsulation dot1Q 1

Router(config-subif)#ip ad

Router(config-subif)#ip address 192.168.1.1 255.255.255.0

Router(config-subif)#no sh

Router(config-subif)#no shutdown

Router(config-subif)#
