The above output shows that the 90:b1:1c:f4:2c:bd MAC address belongs to Dell-1. The 90:b1:1c:f4:29:f3 MAC address belongs to Dell-2.
Also note that these MAC addresses are marked with LOCAL_DA. This means, these are the local destination MAC addresses used by
hosts when routing is required. Packets sent to this MAC address are directly forwarded to their destinations without being sent to the
peer switch.
Dell-2 Switch Conguration
In the following output, RSTP is enabled with a bridge priority of 32768, which is the second lowest in this topology. This ensures that
Dell-2 becomes the root bridge if Dell-1 fails.
