Figure 1-5 Network diagram for MD configuration
Configuration procedure
1) Configuration on Device A (configuration on Device E is the same as that on Device A)
<DeviceA> system-view
[DeviceA] cfd enable
[DeviceA] cfd md MD_A level 5
[DeviceA] cfd ma MA_MD_A md MD_A vlan 100
[DeviceA] cfd service-instance 1 md MD_A ma MA_MD_A
2) Configuration on Device C
<DeviceC> system-view
[DeviceC] cfd enable
[DeviceC] cfd md MD_B level 3
[DeviceC] cfd ma MA_MD_B md MD_B vlan 100
[DeviceC] cfd service-instance 2 md MD_B ma MA_MD_B
3) Configuration on Device B (configuration on Device D is the same as that on Device B)
<DeviceB> system-view
[DeviceB] cfd enable
[DeviceB] cfd md MD_A level 5
[DeviceB] cfd ma MA_MD_A md MD_A vlan 100
[DeviceB] cfd service-instance 1 md MD_A ma MA_MD_A
[DeviceB] cfd md MD_B level 3
[DeviceB] cfd ma MA_MD_B md MD_B vlan 100
[DeviceB] cfd service-instance 2 md MD_B ma MA_MD_B
After the above configuration, you can use the commands display cfd md, display cfd ma and
display cfd service-instance to verify your configuration.
Configuring MEP and Enabling CC on it
Network requirements
After finishing service instance configuration, you can start to design the MEPs.
MEPs are configured at the edge or border of MDs. Find the edge port of each MD.
Decide the MEP direction (inward-facing or outward-facing) on each edge port based on the MD
position.
Assign a unique ID to each MEP in an MA.
