4 管理用以太网口配置ARP MAD典型配置举例（管理功能和MAD功能配置在同一接口）
5 管理用以太网口配置BFD MAD典型配置举例（管理功能和MAD功能配置在不同接口）
8.5.1 搭建IRF（配置Device C和Device D加入IRF）
8.5.2 搭建IRF（配置原IRF和IRF-C合并成IRF）
本文介绍了如何搭建IRF以及在IRF上配置链路聚合和路由功能。
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。
本文档假设您已了解IRF特性。
加入IRF的所有成员设备必须使用相同的软件版本。
在多台设备形成IRF之前，请确保在各设备上以下功能的配置保持一致。
· 最大等价路由条数（通过max-ecmp-num命令配置）。
· 各成员设备的扩展卡插槽的端口速率模式（通过port-speed-mode命令配置）。配置完成后，必须保存配置并重启才能生效。
· 未配置端口隔离功能。
· 组播转发模式（通过fabric multicast-forwarding mode命令配置）。
· 关闭PTP功能。
S6850-G系列、S6805-G系列和S9850-G系列交换机支持QSFP28口用于IRF连接，QSFP28端口拆分的10G口或25G口不支持用于IRF连接。
在S5590-HI、S5590-EI、S5500V3-HI系列交换机上进行IRF端口和IRF物理端口的绑定时，需要注意不同机型对于绑定关系的限制，请参见表3-1。

S5590XP-HI-G系列交换机支持使用10GE/25GE/40GE/100GE光接口作为IRF物理端口。
S6520X-EI-G和S6520XP-EI-G系列交换机支持使用10GE/40GE/100GE光接口作为IRF物理端口。
S5130S-HI-G、S5130S-EI-G、S5100-D-G、S5500-D-G系列交换机支持使用10GE光接口作为IRF物理端口。
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。否则，不能形成IRF。
本章介绍使用管理用以太网口配置ARP MAD，同时不影响网络管理功能使用的配置举例。并且，IRF分裂后，用户可以分别登录到分裂出的IRF上以便进行故障修复。
本举例也适用于ND MAD。仅MAD部分采用相应的配置方法即可。MAD的详细配置方法请参考配置指导。

如图4-1所示，Device A和Device B组成IRF。现要求：
· 使用管理用以太网口M-GigabitEthernet0/0/0配置ARP MAD进行分裂检测，同时不影响网络管理功能的使用；
· IRF主备倒换后，管理员登录用的IP地址不能变化；
· IRF分裂后，允许管理员分别登录到分裂出的成员设备上以进行故障恢复。
图4-1 管理用以太网口配置ARP MAD典型配置举例
主设备管理用以太网接口需要进行如下IP地址配置：
· 使用ip address ip-address { mask-length | mask }命令配置IRF的管理用IP地址。IRF未分裂时请通过此地址登录IRF。IRF发生主备倒换时不影响管理员通过此地址登录IRF。
· 使用ip address ip-address { mask-length | mask } irf-member member-id命令分别配置各成员设备的IP地址。IRF分裂后，管理员可以通过成员设备的IP地址分别登录到分裂出的成员设备上以进行故障恢复。
配置IRF成员设备的IP地址时请注意：
· 同一个管理用以太网接口下配置的所有IRF成员设备的管理用以太网接口地址必须处于同一网段，不同的管理用以太网接口下配置的IRF成员设备的管理用以太网接口地址不能在同一网段。
· 当IRF正常工作时，只有主设备的管理用以太网接口地址生效，从设备的管理用以太网接口地址不生效。如果从设备管理用以太网接口地址与网络中其他设备地址冲突，并不会打印冲突信息，所以需要用户保证配置的管理用以太网接口地址不会冲突。
IRF分裂后，由于分裂出的IRF的管理用以太网接口上均存在ip address ip-address { mask-length | mask }命令配置的IP地址，设备会上报地址冲突，但不影响管理员使用ip address ip-address { mask-length | mask } irf-member member-id命令配置的IP地址分别登录分裂出的IRF设备。
配置ARP MAD时请注意，如果中间设备是一个IRF系统，则必须通过配置确保其IRF域编号与被检测的IRF系统不同。

如图5-1所示，Device A和Device B组成IRF。现要求：
· 使用管理用以太网口M-GigabitEthernet0/0/0接入管理网络；
· 使用管理用以太网口M-GigabitEthernet0/0/1配置BFD MAD进行分裂检测；
· IRF主备倒换后，管理员登录用的IP地址不能变化；
· IRF分裂后，允许管理员分别登录到分裂出的成员设备上以进行故障恢复。
图5-1 管理用以太网口配置BFD MAD典型配置举例
主设备管理用以太网接口M-GigabitEthernet0/0/0需要进行如下IP地址配置：
· 使用ip address ip-address { mask-length | mask }命令配置IRF的管理用IP地址。IRF未分裂时请通过此地址登录IRF。IRF发生主备倒换时不影响管理员通过此地址登录IRF。
· 使用ip address ip-address { mask-length | mask } irf-member member-id命令分别配置各成员设备的IP地址。IRF分裂后，管理员可以通过成员设备的IP地址分别登录到分裂出的成员设备上以进行故障恢复。
配置IRF成员设备的IP地址时请注意：
· 同一个管理用以太网接口下配置的所有IRF成员设备的管理用以太网接口地址必须处于同一网段，不同的管理用以太网接口下配置的IRF成员设备的管理用以太网接口地址不能在同一网段。
· 当IRF正常工作时，只有主设备的管理用以太网接口地址生效，从设备的管理用以太网接口地址不生效。如果从设备管理用以太网接口地址与网络中其他设备地址冲突，并不会打印冲突信息，所以需要用户保证配置的管理用以太网接口地址不会冲突。
IRF分裂后，由于分裂出的IRF的管理用以太网接口上均存在ip address ip-address { mask-length | mask }命令配置的IP地址，设备会上报地址冲突，但不影响管理员使用ip address ip-address { mask-length | mask } irf-member member-id命令配置的IP地址分别登录分裂出的IRF设备。
配置BFD MAD时请注意，
· 请确保中间设备上BFD MAD检测VLAN中仅包含用于BFD MAD检测的端口。
· 在用于BFD MAD检测的接口下必须使用mad ip address命令配置MAD IP地址，而不要配置其它IP地址（包括使用ip address命令配置的普通IP地址、VRRP虚拟IP地址等），以免影响MAD检测功能。请为不同成员设备配置同一网段内的不同MAD IP地址。

· 如图6-1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。

Renumbering the member ID may result in configuration change or loss. Continue?[
Y/N]:y
[DeviceB] quit
<DeviceB> reboot
(2) 根据图6-1选定IRF物理端口并关闭这些端口

+ indicates the device through which the user logs in.
The Bridge MAC of the IRF is: 3822-d60f-2800

从命令行的显示看，当前两台设备IRF成功建立。
(2) 验证跨框聚合有链路备份的作用
从serverGroup 1任意挑选一台PC ping外网IP，关闭IRF的上行端口Ten-GigabitEthernet 1/1/8，出现短暂中断后仍然可以ping通外网。

· 如图7-1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8-3所示。
图8-1 升级之前组网图（两个IRF成员设备）
图8-2 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6 两台成员设备的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。
