CFD configuration example
Network requirements
As shown in
Figure
8 :
• The network comprises five devices and is divided into two MDs: MD_A (level 5) and MD_B (level
3). All ports belong to VLAN 100, and the MAs in the two MDs all serve VLAN 100.
• MD_A has 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, and they are all inward-facing MEPs. MD_B
has two edge ports: GigabitEthernet 1/0/3 on Device B and GigabitEthernet 1/0/1 on Device D,
and they are both outward-facing MEPs.
