本文档介绍了配置两台成员设备的IRF、配置四台成员设备的IRF和IRF扩容升级的配置举例。
IRF（Intelligent Resilient Framework，智能弹性架构）是H3C自主研发的软件虚拟化技术，它的核心思想是将多台设备通过物理IRF端口连接在一起，进行必要的配置后，虚拟化成一台“虚拟设备”，通过该“虚拟设备”来实现多台设备的协同工作、统一管理和不间断维护。
为了便于描述，本文把这个虚拟化形成的设备称为IRF。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
请确保成员设备间的IRF物理连线正确连接，与配置组网图保持一致。
本文假设您已了解IRF特性。
在配置IRF前，S7500X必须满足以下条件，否则不能形成IRF：
· IRF中所有成员设备的主控板型号必须相同。
· IRF中所有成员设备的软件版本必须相同，如果有软件版本不同的设备要加入IRF，请确保IRF的启动文件同步加载功能处于使能状态；
· 如果两个IRF的桥MAC地址相同，请修改其中一个IRF的桥MAC地址，否则，它们不能合并为一个IRF；
· 在多台设备形成IRF之前，请确保各设备上最大等价路由条数的配置保持一致。关于最大等价路由的介绍，请参见“三层技术-IP路由配置指导”中的“IP路由基础配置”；
· 在多台设备形成IRF之前，请确保各设备的工作模式相同。关于工作模式的配置，请参见“基础配置指导”中的“设备管理配置”。
本设备上与IRF-Port1绑定的IRF物理端口只能和邻居成员设备IRF-Port2口上绑定的IRF物理端口相连，本设备上与IRF-Port2口绑定的IRF物理端口只能和邻居成员设备IRF-Port1口上绑定的IRF物理端口相连，如表1所示。否则，不能形成IRF。

IRF物理端口可以选择10GE/40GE/100GE以太网光口。
· 在使用LSQM2TGS16SF0或LSQM1TGS12EC0单板上的端口作为IRF物理端口与IRF端口绑定时，需要注意端口的分组使用方式：
¡ 对于LSQM2TGS16SF0单板，编号为1、2、15、16的端口为一个端口一组，编号为3、4、5的端口为一组，编号为6、7、8的端口为一组，编号为9、10、11的端口为一组，编号为12、13、14的端口为一组。
¡ 对于LSQM1TGS12EC0单板，从第一个10GE端口的编号开始，按端口编号由小到大的顺序，每4个连续的端口分为一组。
¡ 同一组中的所有端口用途必须相同，即当组内某一端口与IRF端口绑定后，该组中其它端口也必须与IRF端口绑定，不能再作为普通业务端口使用，反之亦然。
¡ 在将组内某个端口与IRF端口进行绑定或取消绑定之前，必须先对该端口所在组内的所有端口执行shutdown操作，在完成绑定或取消绑定操作后，再对同组内所有端口执行undo shutdown操作。
· 如果使用using tengige命令将一个40GE接口拆分成四个10GE接口，这四个10GE接口将分作一组，如果直接使用40GE端口作为IRF物理端口，则不需要考虑端口的分组。
· 当选用具有40GE QSFP+端口的单板进行IRF连接时，由于40GE QSFP+端口具备拆分成4个10GE端口的功能，当执行拆分或合并操作时需要重启该单板，因此请提前规划好40GE QSFP+端口的使用方式，避免IRF形成后重启单板可能对IRF拓扑产生的影响。
· 在独立运行模式下将IRF端口和IRF物理端口绑定，并不会影响IRF物理端口的当前业务。当设备切换到IRF模式后，IRF物理端口的配置将恢复到缺省状态（即原有的业务配置会被删除），IRF物理端口下只能配置以下命令：
¡ 接口配置命令，包括shutdown、description和flow-interval命令。有关这些命令的详细介绍，请参见“接口管理命令参考”中的“以太网接口”。
¡ LLDP功能命令，包括lldp admin-status、lldp check-change-interval、lldp enable、lldp encapsulation snap、lldp notification remote-change enable和lldp tlv-enable。有关这些命令的详细介绍，请参见“二层技术-以太网交换配置指导”中的“LLDP”。
· MAC配置命令，包括mac-address static source-check enable命令。为了保证跨成员设备的三层报文的正常转发，请在每个IRF物理端口下配置undo mac-address static source-check enable命令。有关命令的详细介绍，请参见“二层技术——以太网交换”中的“MAC地址表”。
本系列交换机最多支持使用四台设备建立IRF。
LACP MAD和BFD MAD、ARP MAD、NDMAD冲突处理的原则不同，请不要同时配置。BFD MAD和ARP MAD、ND MAD冲突处理的原则不同，并且BFD MAD和生成树协议互斥，ARP MAD、ND MAD需要开启生成树协议，因此BFD MAD和ARP MAD、ND MAD无法同时配置。
请确保IRF中各成员设备上安装的特性License一致，否则，可能会导致这些License对应的特性不能正常运行。
· 如图1所示，Device A为公司的核心设备，但由于公司网络规模日益增大，汇聚层SW设备扩展至N台，Device A单台设备的转发能力已无法达到公司网络的需求。为了拓展核心设备的转发能力，又尽量不改变现有网络。现公司希望增加Device B，与Device A组成IRF，来满足当前网络的需求。
· IRF的上行设备（Router A和Router B）为公司网络的出口路由器；IRF的下行交换机（SW 1、SW 2等）为各个服务器集群的汇聚层设备。

· 为避免成员设备的单点故障影响到正常的业务转发，可在IRF中配置跨框聚合端口进行业务转发。
· 为尽量降低IRF分裂对业务造成的影响，可在IRF中配置LACP MAD检测。LACP MAD检测只需在一个聚合组中配置即可，其他聚合组中无需配置。LACP MAD检测使用的中间设备必须为H3C的交换机设备且使用的软件版本必须能够识别、处理携带了ActiveID值的LACPDU协议报文，在本例中使用SW 1作为LACP MAD检测的中间设备。
(1) 设置Device A的成员编号为1
<DeviceA> system-view

Now rebooting, please wait...
在前面配置完成并重新启动后，IRF已经组建完成，此时可以进行各个业务模块的配置。IRF形成之后，可以从任何一台成员设备登录进行配置，设备名称缺省为Master的名称（此例中为Device A）。

重新开启端口Ten-GigabitEthernet 1/3/0/8，持续ping，将另外一个上行端口Ten-GigabitEthernet 2/3/0/8关闭，出现短暂中断后仍然可以ping通外网。

· 如图2所示，由于网络规模迅速扩大，汇聚层SW设备扩展至N台，当前中心设备Device A的转发能力已经不能满足需求。现在需要另增三台设备，组成一个四框IRF才能满足当前网络的转发需求。
· 升级到四框IRF设备后，必须保证即使IRF中有N台设备发生故障（1≤N≤3），RouterA与汇聚层交换机（如：SW1，SW2等）之间通信也不能中断。

· 为避免成员设备的单点故障影响到正常的业务转发，可在IRF中配置跨框聚合端口进行业务转发。
· LACP MAD检测只需在一个聚合组中配置即可，其他聚合组中无需配置。LACP MAD检测使用的二层交换机必须为H3C的交换机设备且使用的软件版本必须能够识别、处理携带了ActiveID值的LACPDU协议报文，在本例中使用SW 1作为LACP MAD检测的中间设备。

由于网络规模迅速扩大，汇聚层SW设备扩展至N台，当前中心设备Device A和Device B组成IRF的转发能力已经不能满足需求。现在需要在保留原有设备的基础上完成扩容，满足当前网络的转发需求。采用的升级方案为：扩大汇聚层设备的IRF规模，升级成四框IRF来满足当前网络的转发需求，如图5所示。
图3 升级之前组网图（两个IRF成员设备）
图4 升级过程组网图（新增两个成员设备Device C和Device D）
IP地址配置信息及设备间的互联端口信息请参见5 四台成员设备的IRF配置举例。
· 为避免成员设备的单点故障影响到正常的业务转发，在IRF中配置跨框聚合端口进行业务转发。
· 为尽量降低IRF分裂对业务造成的影响，可在IRF中配置BFD MAD检测。检测速度较快，组网形式灵活，对于中间设备没有要求，但是会占用额外的三层接口。
BFD MAD与STP功能互斥，因此需要在用于BFD MAD检测的接口上关闭STP功能。
· 如果新加入的DeviceC和DeviceD都是独立运行模式，搭建四框IRF的配置步骤请参考6.4.1 搭建IRF（配置DeviceC和DeviceD加入IRF）；
· 如果新加入的DeviceC和DeviceD已经组成了另一个IRF（假设名称为IRF-C），搭建四框IRF的配置步骤请参考6.4.2 搭建IRF（配置原IRF和IRF-C合并成IRF）。
由于DeviceA和DeviceB已经组成了IRF，所以只需将DeviceC和DeviceD加入IRF即可。
