Network requirements
As shown in
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-FC00-651 1, 0010-FC00-6512,
0010-FC00-6513, 0010-FC00-6514, and 0010-FC00-6515, respectively.
MD_A has three edge ports: Ten-GigabitEthernet 1/1/5 on Device A, Ten-GigabitEthernet 1/1/7
•
on Device D, and Ten-GigabitEthernet 1/1/8 on Device E, and they are all inward-facing MEPs.
MD_B has two edge ports: Ten-GigabitEthernet 1/1/7 on Device B and Ten-GigabitEthernet
1/1/5 on Device D, and they are both outward-facing MEPs.
