NOTE
When the default DIS priority is used,
l The MAC address of the interface on SwitchB is the largest one among that of the interfaces on
the Level-1 Switches. Thus, SwitchB is elected as the Level-1 DIS.
l The MAC address of the interface on SwitchD is the largest one among that of the interfaces on
the Level-2 Switches. Thus, SwitchD is elected as the Level-2 DIS.
The Level-1 pseudonode is 0000.0000.0002.01. The Level-2 pseudonode is 0000.0000.0004.01.
5. Configure the DIS priority of SwitchA.
