3. 配置步骤

(1)     配置Device A

# 配置接口IP地址、路由、安全域及域间策略保证网络可达，具体配置步骤略。

# 配置IRF中成员编号为1的设备的优先级为32。

<DeviceA> system-view

[DeviceA] irf member 1 priority 32

# 配置IRF端口1/2，并将它与物理端口Ten-GigabitEthernet1/2/5/2绑定，并保存配置。

[DeviceA] interface ten-gigabitethernet 1/2/5/2

[DeviceA-Ten-GigabitEthernet1/2/5/2] shutdown

[DeviceA-Ten-GigabitEthernet1/2/5/2] quit

[DeviceA] irf-port 1/2

[DeviceA-irf-port1/2] port group interface ten-gigabitethernet 1/2/5/2

[DeviceA-irf-port1/2] quit

[DeviceA] interface ten-gigabitethernet 1/2/5/2

[DeviceA-Ten-GigabitEthernet1/2/5/2] undo shutdown

[DeviceA-Ten-GigabitEthernet1/2/5/2] quit

[DeviceA] save

# 激活IRF端口下的配置。

[DeviceA] irf-port-configuration active

(2)     配置Device B

# 配置接口IP地址、路由、安全域及域间策略保证网络可达，具体配置步骤略。

# 配置设备的运行模式为IRF模式，设备若已运行在IRF模式下，输入模式切换命令会提示The device is already in IRF mode。修改运行模式后，设备会自动重启使新的模式生效，请注意保存配置。

<DeviceB> system-view

[DeviceB] chassis convert mode irf

You are recommended to save the current running configuration and specify the configuration file for the next startup. Continue? [Y/N]:y

Do you want to convert the content of the next startup configuration file flash:/startup.cfg to make it available in IRF mode? [Y/N]:y

Now rebooting, please wait...

# 将Device B的成员编号配置为2，并重启设备使新编号生效。

<DeviceB> system-view

[DeviceB] irf member 1 renumber 2

Warning: Renumbering the member ID may result in configuration change or loss. Continue? [Y/N]:y

[DeviceB] quit

<DeviceB> reboot

# 参照配置组网图进行物理连线。

# 重新登录到设备，配置IRF端口2/1，将它与物理端口Ten-GigabitEthernet2/2/5/2绑定，并保存配置。

<DeviceB> system-view

[DeviceB] interface ten-gigabitethernet 2/2/5/2

[DeviceB-Ten-GigabitEthernet2/2/5/2] shutdown

[DeviceB-Ten-GigabitEthernet2/2/5/2] quit

[DeviceB] irf-port 2/1

[DeviceB-irf-port2/1] port group interface ten-gigabitethernet 2/2/5/2

[DeviceB-irf-port2/1] quit

[DeviceB] interface ten-gigabitethernet 2/2/5/2

[DeviceB-Ten-GigabitEthernet2/2/5/2] undo shutdown

[DeviceB-Ten-GigabitEthernet2/2/5/2] quit

[DeviceB] save

# 激活IRF端口下的配置。

[DeviceB] irf-port-configuration active

(3)     Device A和Device B间将会进行主设备竞选，竞选失败的一方（Device B）将重启，重启完成后，IRF形成。

(4)     配置LACP MAD检测

# 设置IRF域编号为1。

[DeviceA] irf domain 1

# 创建一个动态聚合接口，并开启LACP MAD检测功能。

[DeviceA] interface route-aggregation 2

[DeviceA-Route-Aggregation2] link-aggregation mode dynamic

[DeviceA-Route-Aggregation2] mad enable

You need to assign a domain ID (range: 0-4294967295)

[Current domain is: 1]:

The assigned domain ID is: 1

MAD LACP only enable on dynamic aggregation interface.

[DeviceA-Route-Aggregation2] quit

# 在聚合接口中添加成员端口GigabitEthernet1/2/5/1和GigabitEthernet2/2/5/1，用于Device A和Device B实现LACP MAD检测。

[DeviceA] interface gigabitethernet 1/2/5/1

[DeviceA-GigabitEthernet1/2/5/1] port link-aggregation group 2

[DeviceA-GigabitEthernet1/2/5/1] quit

[DeviceA] interface gigabitethernet 2/2/5/1

[DeviceA-GigabitEthernet2/2/5/1] port link-aggregation group 2

[DeviceA-GigabitEthernet2/2/5/1] quit

(5)     配置中间设备Device C

# 配置接口IP地址、路由保证网络可达，具体配置步骤略。

# 创建一个动态聚合接口。

<DeviceC> system-view

[DeviceC] interface route-aggregation 2

[DeviceC-Route-Aggregation2] link-aggregation mode dynamic

[DeviceC-Route-Aggregation2] quit

# 在聚合接口中添加成员端口Ten-GigabitEthernet1/0/1和Ten-GigabitEthernet1/0/2，用于帮助LACP MAD检测。

[DeviceC] interface ten-gigabitethernet 1/0/1

[DeviceC-Ten-GigabitEthernet1/0/1] port link-aggregation group 2

[DeviceC-Ten-GigabitEthernet1/0/1] quit

[DeviceC] interface ten-gigabitethernet 1/0/2

[DeviceC-Ten-GigabitEthernet1/0/2] port link-aggregation group 2

[DeviceC-Ten-GigabitEthernet1/0/2] quit

4. 验证配置

·     IRF链路正常情况下查看相关配置

# 查看IRF相关信息，可见IRF成功建立，且DeviceA为主设备。

[DeviceA] display irf
