All ports belong to VLAN 100, and the MAs in the two MDs all serve VLAN 100. Assume thatthe MAC addresses of Device A through Device E are 0010-FC00-6511, 0010-FC00-6512,0010-FC00-6513, 0010-FC00-6514, and 0010-FC00-6515, respectively.• MD_A has three edge ports: GigabitEthernet 1/0/1 on Device A, GigabitEthernet 1/0/3 onDevice D, and GigabitEthernet 1/0/4 on Device E. They are all inward-facing MEPs. MD_B hastwo edge ports: GigabitEthernet 1/0/3 on Device B and GigabitEthernet 1/0/1 on Device D.They are both outward-facing MEPs.• In MD_A, Device B is designed to have MIPs when its port is configured with low-level MEPs. PortGigabitEthernet 1/0/3 is configured with MEPs of MD_B, and the MIPs of MD_A can beconfigured on this port. Configure the MIP generation rule of MD_A as explicit.
