7配置文件·477相关资料5411简介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(IntelligentResilientFramework,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.
2配置前提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.
3使用限制1.
IRF形成条件在配置IRF前,S10500必须满足以下条件,否则不能形成IRF: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".
2.
IRF连接限制本设备上与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.
表1IRF物理端口连接限制邻居成员设备上的IRF物理端口本设备上的IRF物理端口IRF-Port1绑定的IRF物理端口IRF-Port2绑定的IRF物理端口IRF-Port1绑定的IRF物理端口不能连接可以连接2邻居成员设备上的IRF物理端口本设备上的IRF物理端口IRF-Port1绑定的IRF物理端口IRF-Port2绑定的IRF物理端口IRF-Port2绑定的IRF物理端口可以连接不能连接3.
IRF物理端口选择限制在使用SF或EC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: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undoshutdown操作.
SF或EC单板上的端口的分组方式为:如果使用usingtengige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.
对于LSUM2TGS16SF0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.
在其它提供10GE端口的SF或EC单板上,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.
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40GEQSFP+端口的单板进行IRF连接时,由于40GEQSFP+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40GEQSFP+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shutdown、description和flow-interval命令.
有关shutdown、description和flow-interval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"以太网接口".
4.
IRF最大成员设备数限制本系列交换机最多支持使用四台设备建立IRF.
5.
MAD使用限制LACPMAD和BFDMAD、ARPMAD、NDMAD冲突处理的原则不同,请不要同时配置.
BFDMAD、ARPMAD和NDMAD这三种方式独立工作,彼此之间互不干扰,可以同时配置.
6.
License使用限制请确保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.
34两台成员设备的IRF配置举例4.
1组网需求如图1所示,DeviceA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,DeviceA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DeviceB,与DeviceA组成IRF,来满足当前网络的需求.
IRF的上行设备(RouterA和RouterB)为公司网络的出口路由器;IRF的下行交换机(SW1、SW2等)为各个服务器集群的汇聚层设备.

2配置思路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LACPMAD检测.
LACPMAD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.
LACPMAD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SW1作为LACPMAD检测的中间设备.

1组网需求由于网络规模迅速扩大,汇聚层SW设备扩展至N台,当前中心设备设备A和设备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)IRFDeviceBDeviceA……SW1SW2SWNGE3/0/1GE3/0/1GE3/0/1ServerGroup1ServerGroup2ServerGroupXXXServerGroupN……RouterA36图4升级过程组网图(新增两个成员设备DeviceC和DeviceD)IRFDeviceBDeviceA……SW1SW2SWNGE3/0/1GE3/0/1GE3/0/1ServerGroup1ServerGroup2ServerGroupXXXServerGroupN……DeviceCDeviceDRouterA37图5升级之后组网图(采用BFDMAD)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.
6.
2配置思路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BFDMAD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.
IRFDeviceBDeviceA……SW1SW2SWNGE3/0/1GE3/0/1GE3/0/1ServerGroup1ServerGroup2ServerGroupXXXServerGroupN……DeviceCDeviceDRouterAL2Switch386.
3使用版本本举例在S10500-CMW710-R7150版本上进行配置和验证.
6.
4配置注意事项BFDMAD与STP功能互斥,因此需要在用于BFDMAD检测的接口上关闭STP功能.
6.
5配置步骤如果新加入的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.
5.
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.
5.
2搭建IRF(配置原IRF和IRF-C合并成IRF).
6.
5.
1搭建IRF(配置DeviceC和DeviceD加入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.

3BFDMAD配置在前面配置完成并重新启动后,IRF已经形成,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DeviceA).
使能BFDMAD检测时,要求MADVLAN上不能配置其他业务.

但是在实际使用中,部分在升级之前已经部署的业务可以无需再重新配置了(例如端口IP地址等).
