交换机IRF的BFD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GigabitEthernet1/0/1和GigabitEthernet2/0/1，用于Device A和Device B实现LACP MAD检测。

[DeviceA] interface gigabitethernet 1/0/1

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

[DeviceA-GigabitEthernet1/0/1] quit

[DeviceA] interface gigabitethernet 2/0/1

[DeviceA-GigabitEthernet2/0/1] port link-aggregation group 2

[DeviceA-GigabitEthernet2/0/1] 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GigabitEthernet1/0/1和GigabitEthernet1/0/2，用于帮助LACP MAD检测。

[DeviceC] interface gigabitethernet 1/0/1

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

[DeviceC-GigabitEthernet1/0/1] quit

[DeviceC] interface gigabitethernet 1/0/2

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

[DeviceC-GigabitEthernet1/0/2] quit

您好，请知：

可以三层来实现IRF BFD检测。
