一、实验内容
1、组网图
2、配置操作
2.1 配置设备编号
A设备保留成员编号为1，不需要配置，同时，将B设备的成员编号改为2
[server-B]irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
Please reboot the device for the new member ID to take effect.
[server-B]quit
<server-B>reboot # 改完编号后需要重启设备，才会生效
Start to check configuration with next startup configuration file, please wait.........DONE!
Current configuration may be lost after the reboot, save current configuration? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
This command will reboot the device. Continue? [Y/N]:y
2.2 配置堆叠口

<server-A>sys # 进入系统试图
System View: return to User View with Ctrl+Z.
[server-A]int range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50 # 批量进入端口
[server-A-if-range]shutdown # 关闭端口
[server-A-if-range]quit # 返回
[server-A]irf-port 1/2 # 创建设备的IRF端口2，与物理口49和50进行绑定
[server-A-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/49
[server-A-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50
[server-A-irf-port1/2]display this # 查看IRF是否和物理端口绑定成功

[server-A-irf-port1/2]quit
[server-A]int rang Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
[server-A-if-range]undo shutdown # 绑定成功后，打开端口
[server-A-if-range]quit
[server-A]save force # 保存配置

2.2.2 设备B
<server-B>sys
System View: return to User View with Ctrl+Z.
[server-B]int range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
[server-B-if-range]shutdown[server-B-if-range]quit
[server-B]irf-port 2/1

[server-B]int range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50

Saved the current configuration to mainboard device successfully.# 激活设备A的IRF端口配置
[server-A]irf-port-configuration active
# 激活设备B的IRF端口配置
[server-B]irf-port-configuration active
# 两台设备间将会进行Master竞选，竞选失败的一方将自动重启，重启完成后，IRF形成，系统名称统一为severA
display irf link 检查连接是否成功
3、 BFD分裂检测
# IRF设备一旦分裂，会变成两台配置完全相同的设备，导致业务转发有问题。为了避免此类问题出现，可以配置分裂检测。设备一旦检测到IRF2分裂，则自动关闭备设备的所有非保留端口。在此介绍BFD MAD分裂检测配置方法。使用网线server A上的端口GigabitEthernet1/0/1和server B上的端口GigabitEthernet2/0/1连接起来。
# 创建VLAN 3，并将server A上的端口GigabitEthernet1/0/1和server B上的端口GigabitEthernet2/0/1加入VLAN中。
<server-A> system-view
[server-A] vlan 3
[server-A-vlan3] port gigabitethernet 1/0/1 gigabitethernet 2/0/1
[server-A-vlan3] quit
# 创建VLAN接口3，并配置MAD IP地址。
[server-A] interface vlan-interface 3
[server-A-Vlan-interface3] mad bfd enable
[server-A-Vlan-interface3] mad ip address 10.0.0.1 24 member 1
[server-A-Vlan-interface3] mad ip address 10.0.0.2 24 member 2
[server-A-Vlan-interface3] quit
# 按组网图所示连接BFD MAD链路。
#因为BFD MAD和生成树互相排斥，所以要在接口g1/0/1和g2/0/1上关闭stp
[server-A] interface gigabitethernet 1/0/1
[server-A-Gigabitethernet1/0/1] undo stp enable
[server-A-Gigabitethernet1/0/1] quit
[server-A] interface gigabitethernet 2/0/1
[server-A-Gigabitethernet2/0/1] undo stp enable
4、配置要点
1、IRF-port端口编号说明，irf-port 1/2中，第一个数字代表的是设备成员编号，第二个数字是接口编号。堆叠要求使用逻辑端口1对接逻辑端口2。即，如若第一台配置irf-port1/2，则第二台需要是用irf-port2/1对接。如若第一台使用irf-port1/1，则第二台需要配置irf-port2/2。
2、设备配置好IRF2配置后，要先保存再激活配置。
