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 Router A through Router E are 0010-FC00-6511,
0010-FC00-6512, 0010-FC00-6513, 0010-FC00-6514, and 0010-FC00-6515, respectively.
