2、堆叠”技术。三个优点：简化管理高可用性灵活扩展网络组网架构如图上1所示，MaSterSlave组成IRF,对上、下层设备来说，它们就是一台设备IRF。图I-IIRF组网应用示意图IRF的连接拓扑有两种：链形连接和环形连接，如图1-5所示。相比环形连接，链形连接对成员设备的物理位置要求更低，主要用于成员设备物理位置分散的组网。环形连接比链形连接更可靠。因为当链形连接中出现链路故障时，会引起IRF分裂；而环形连接中某条链路故障时，会形成链形连接，IRF的业务不会受到影响。IRF-PortaIRFIRF-PortI辉彩注法IRF链形堆叠swl:irfmember1priority5将SWl优先级配置
