[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
Configuration on Device C
[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
Configuration on Device B (configuration on Device D is the same as that on Device B)
[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
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
Assign a unique ID to each MEP in an MA.
Decide the remote MEP for each MEP, and enable these MEPs.
According to the network diagram as shown in
In MD_A, there are three edge ports: GigabitEthernet 1/0/1 on Device A, GigabitEthernet 1/0/3 on
Device D and GigabitEthernet 1/0/4 on Device E. Configure inward-facing MEPs on these ports
In MD_B, there are two edge ports: GigabitEthernet 1/0/3 on Device B and GigabitEthernet 1/0/1
on Device D. Configure outward-facing MEPs on the two ports respectively.
In MD_A and MD_B, each MEP checks the messages from other MEPs.
1-6, perform the following configurations:
