要求:在S3、S4交换机中引入路由时,需要进行路由标记。其中,生产网段(vlan10)标记为10;办公网段(vlan20)标记为20。因业务联通需要,所有增加的网络终端数据之间的通信,一并划入办公网段进行路由标记,路由图定义为SET_TAG
S3(config)#route-map SET_TAG permit 10
S3(config-route-map)#match interface vlan 10
S3(config-route-map)#set tag 10
S3(config-route-map)#exit
S3(config)#route-map SET_TAG permit 20
S3(config-route-map)#match interface vlan 20
S3(config-route-map)#set tag 20
S3(config-route-map)#exit
S3(config)#router ospf 1
S3(config-router)#redistribute connected subnets metric-type 1 route-map SET_TAG
S4(config)#route-map SET_TAG permit 10
S4(config-route-map)#match interface vlan 10
S4(config-route-map)#set tag 10
S4(config-route-map)#exit
S4(config)#route-map SET_TAG permit 20
S4(config-route-map)#match interface vlan 20
S4(config-route-map)#set tag 20
S4(config-route-map)#exit
S4(config)#router ospf 1
S4(config-router)#redistribute connected subnets metric-type 1 route-map SET_TAG
