基于IP子網(wǎng)劃分VLAN配置示例

1、基于IP子網(wǎng)劃分VLAN配置示例51、組網(wǎng)需求Router A1/0/3RouterCGE1/(W>J>X，GE 1 /0/4 SwitchInternetGE1/0/5Voice NetworkGE 1/0/7192 J 68.12192.168.22圖1基于IP子網(wǎng)劃分VLAN&網(wǎng)圖如圖1所示，某企業(yè)擁有多種業(yè)務(wù)，如IPTV、VoIP、Internet等，每種業(yè)務(wù)使用的IP地址網(wǎng)段各不相同。為了便于管理，現(xiàn)需要將同一種類型業(yè)務(wù)劃分到同一VLAN中，不同類型的業(yè)務(wù)劃分到不同VLAN中。Switch接收到用戶報(bào)文有數(shù)據(jù)、IPTV、語音等多種業(yè)務(wù)，用戶設(shè)備的IP地址網(wǎng)段各不相

2、同?，F(xiàn)需要將不同類型的業(yè)務(wù)劃分到不同的VLAN中，通過不同的VLANID分流到不同的遠(yuǎn)端服務(wù)器上以實(shí)現(xiàn)業(yè)務(wù)互通。2、配置思路2.1、 創(chuàng)建VLAN確定每種業(yè)務(wù)所屬的VLAN2.2、 關(guān)聯(lián)IP子網(wǎng)和VLAN實(shí)現(xiàn)根據(jù)報(bào)文中的源IP地址或指定網(wǎng)段確定VLAN2.3、 配置接口加入VLAN實(shí)現(xiàn)基于IP子網(wǎng)的VLANS過當(dāng)前接口。2.4、 使能基于IP子網(wǎng)劃分VLAN3、操作步驟3.1、 創(chuàng)建VLAN#在Switch上創(chuàng)建VLAN100VLAN20阱口VLAN3001. <HUAWEI>system-view2.
