業(yè)網(wǎng)OSPF分流  組網(wǎng)需求： 實現(xiàn)拓撲圖中的生產(chǎn)業(yè)務(wù)與辦公業(yè)務(wù)分流。 IP地址規(guī)劃如下：   －、基本信息及鏈路配置，連通性測試（略） 二、總部二層網(wǎng)絡(luò)業(yè)務(wù)分流策略部署 配置如下： SW1,SW2上分別創(chuàng)建vlan20,21,22,300,901 SW3創(chuàng)建vlan20,21,22,300 SW9、SW10創(chuàng)建vlan 36、37、300 生成樹的配置，總部生產(chǎn)和網(wǎng)管以SW1為根，辦公以SW2為根，互作備份。 SW1： spanning-tree vlan 1 priority 0 spanning-tree vlan 20 priority 0 spanning-tree vlan 21 priority 4096 spanning-tree vlan 22 priority 0 spanning-tree vlan 23 priority 4096 spanning-tree vlan 300 priority 0 no spanning-tree vlan 901 //901作為互聯(lián)VLAN，需關(guān)閉生成樹 SW2： spanning-tree vlan 1 priority 4096 spanning-tree vlan 20 priority 4096 spanning-tree vlan 21 priority 0 spanning-tree vlan 22 priority 4096 spanning-tree vlan 23 priority 0 spanning-tree vlan 300 priority 4096 no spanning-tree vlan 901 //901作為互聯(lián)VLAN，需關(guān)閉生成樹 SW3上的STP使用默認值就行了，現(xiàn)在VLAN1,20,22,300是走SW1,VLAN21,23走SW2. 總部HSRP/VRRP的配置：生產(chǎn)網(wǎng)管以SW1為主網(wǎng)關(guān)，辦公以SW2為主網(wǎng)關(guān)，互作備份 SW1：interface Vlan20 standby 20 ip 172.16.20.1 standby 20 priority 200 standby 20 preempt interface Vlan21 standby 21 ip 172.16.21.1 standby 21 preempt interface Vlan22 standby 22 ip 172.16.22.1

分部HSRP/VRRP的配置：生產(chǎn)網(wǎng)管以RT7為主網(wǎng)關(guān)，辦公以RT8為主網(wǎng)關(guān)，互作備份 RT7： interface FastEthernet2/0 ip address 172.16.35.2 255.255.255.0 vrrp 19 ip 172.16.35.1 vrrp 19 priority 150

總部生產(chǎn)訪問辦公生產(chǎn)：VPC3-SW3-SW1-RT5-RT7-SW9-VPC5 總部生產(chǎn)訪問分部辦公：VPC3-SW3-SW1-SW2-RT6-RT8-SW10 其它的大家慢慢去測試下吧！ |
