交换机vrrp加mstp配置实例组网需求switcha、switchb选用两台锐捷的s5750;switchc、shwichd选用锐捷的s3750和s3760全网共有两个业务vlan,为vlan10、vlan20Switcha、switchb都分别对两vlan起用两vrrp组,实现两组的业务的负载分担和备份。Switcha、switchb、switchc、switchd都起用mstp多生成数协议,并且所有设备都属于同一个mst域,且实例映射一致(vlan10映射实例1、vlan20映射实例2其他vlan映射默认实例0)。Vlan10业务以switcha为根桥;vlan20业务以switchb为根桥;实现阻断网络环路,并能实现不同vlan数据流负载分担功能。组网图配置步骤Switcha配置:s1#showrunBuildingconfiguration...Currentconfiguration:1651bytes!(2),Release(29287)(TueDec2520:39:14CST2007-ngcf49)hostnames1co-operateenable!!!vlan1!vlan10!vlan20!!noservicepassword-encryption!spanning-tree开启生成树(默认为mstp)spanning-treemstconfiguration进入mst配置模式revision1指定MSTrevisionnumber为1nameregion1指定mst配置名称instance0vlan1-9,11-19,21-4094缺省情况下vlan都属于实例0instance1vlan10手工指定vlan10属于实例1instance2vlan20手工指定vlan20属于实例2spanning-treemst1priority0指定实例1的优先级为0(为根桥)spanning-0/essvlan10配置g0/1属于vlan10!0/essvlan20配置g0/2属于vlan20!0/3!..0/24设置g0/24为trunk接口且允许vlan10/20通过switchportmodetrunk!!!linecon0linevty04logins1#showvlanVLANNameStatusPorts-------------------------------------------------------------------------------1VLAN0001STATICGi0/3,Gi0/4,Gi0/5,Gi0/6Gi0/7,Gi0/8,Gi0/9,Gi0/10Gi0/11,Gi0/12,Gi0/13,Gi0/14Gi0/15,Gi0/16,Gi0/17,Gi0/18Gi0/19,Gi0/20,Gi0/21,Gi0/22Gi0/23,Gi0/2410VLAN0010STATICGi0/1,Gi0/2420VLAN0020STATICGi0/2,Gi0/24Switchb配置:s2#showrunBuildingconfiguration...Currentconfiguration:1607bytes!(2),Release(27932)(ThuDec1310:32:09CST2007-ngcf31)hostnames2!!!vlan1!vlan10!vlan20!!noservicepassword-encryption!spanning-treespanning-treemstconfigurationrevision1nameregion1instance0vlan1-9,11-19,21-4094instance1vlan10instance2vlan20spanning-treemst1priority4096spanning-0/essvlan10!0/essvlan20!..0/24switchportmodetrunk!interfa
