交換機 vrrp+mstp配置實例

1、交換機 vrrp+mstp配置實例銳捷tac賈文宇一、 組網(wǎng)需求1、 switch a 、switch b選用兩臺銳捷的s5750 ；switch c 、shwich d 選用銳捷的 s3750和s37602、 全網(wǎng)共有兩個業(yè)務vlan ,為 vlan 10 、vlan 203、 Switch a 、switch b 都分別對兩vlan起用兩vrrp組，實現(xiàn)兩組的業(yè)務的負載分擔和備份。4、 Switch a、switch b、switch c、switch d 都起用 mstp多生成數(shù)協(xié)議，并且所有設備都屬于同一個mst域，且實例映射一致（vlan 10映射實例1、vlan 20映射實例2 其

2、他vlan映射默認實例0）。5、 Vlan 10業(yè)務以switch a為根橋； vlan 20業(yè)務以switch b為根橋；實現(xiàn)阻斷網(wǎng)絡環(huán)路，并能實現(xiàn)不同vlan數(shù)據(jù)流負載分擔功能。二、 組網(wǎng)圖三、 配置步驟Switch a配置：s1#show runBuilding configuration.Current configuration : 1651 bytes!version RGNOS 10.2.00(2), Release(29287)(Tue Dec 25 20:39:14 CST 2007 -ngcf49)hostname s1co-operate enable!vlan 1!vl
