Network requirements
As shown in Figure 6:
• 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. Assume that
the MAC addresses of Device A through Device E are 0010-FC00-6511, 0 010 - FC 00 - 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 on
Device D, and GigabitEthernet 1/0/4 on Device E. 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.
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. Port
GigabitEthernet 1/0/3 is configured with MEPs of MD_B, and the MIPs of MD_A can be
configured on this port. Configure the MIP generation rule of MD_A as explicit.
