全面分析路由交換機(jī)配置實(shí)例應(yīng)用
了解一些關(guān)于路由交換機(jī)配置的知識(shí)還是非常有用的,這里我們主要介紹路由交換機(jī)配置實(shí)例應(yīng)用,在局域網(wǎng)中,通過(guò)路由交換機(jī)配置VLAN可以減少主機(jī)通信廣播域的范圍。
當(dāng)VLAN之間有部分主機(jī)需要通信,但交換機(jī)不支持三層交換時(shí),可以采用一臺(tái)支持802.1Q的路由交換機(jī)配置實(shí)現(xiàn)VLAN的互通.這需要在以太口上建立子接口,分配IP地址作為該VLAN的網(wǎng)關(guān),同時(shí)啟動(dòng)802.1Q。組網(wǎng):路由器E0端口與交換機(jī)的上行trunk端口(第24端口)相連,交換機(jī)下行口劃分3個(gè)VLAN,帶若干主機(jī)。拓?fù)鋱D如下:
1.路由交換機(jī)配置
- [Router]
- [Router]inter e0
- [Router-Ethernet0]ip add 10.0.0.1 255.255.255.0
- [Router-Ethernet0]inter e0.1 //定義子接口E0.1
- [Router-Ethernet0.1]ip add 172.16.1.1 255.255.255.0
- [Router-Ethernet0.1]vlan-type dot1q vid 1 //指定以太網(wǎng)子接口屬于VLAN1,此命令應(yīng)用在以太網(wǎng)子接口上。
- [Router-Ethernet0.1]inter e0.2 //定義子接口E0.2
- [Router-Ethernet0.2]ip add 172.16.2.1 255.255.255.0
- [Router-Ethernet0.2]vlan-type dot1q vid 2 //指定以太網(wǎng)子接口屬于VLAN2
- [Router-Ethernet0.2]inter e0.3 //定義子接口E0.3
- [Router-Ethernet0.3]ip add 172.16.3.1 255.255.255.0
- [Router-Ethernet0.3]vlan-type dot1q vid 3 //指定以太網(wǎng)子接口屬于VLAN3
- [Router-Ethernet0.3]inter e0
- [Router-Ethernet0]undo shut
- % Interface Ethernet0 is up
- [Router-Ethernet0] //用網(wǎng)線將E0端口連到S3026第24端口
- %19:46:32: Interface Ethernet0 changed state to UP
- %19:46:32: Line protocol ip on interface Ethernet0, changed state to UP
- %19:46:32: Line protocol ip on interface Ethernet0.1, changed state to UP
- %19:46:32: Line protocol ip on interface Ethernet0.2, changed state to UP
- %19:46:32: Line protocol ip on interface Ethernet0.3, changed state to
2.交換機(jī)的配置
- <Quidway>
- <Quidway>sys
- Enter system view , return user view with Ctrl+Z.
- [Quidway]vlan 1
- [Quidway-vlan1]vlan 2
- [Quidway-vlan2]port ethernet 0/17 to eth 0/19 eth 0/22
- [Quidway-vlan2]vlan 3
3.在工作站上檢查網(wǎng)絡(luò)是否連通。此工作站連接S3026第21端口,屬于VLAN2。
