With the MAC address replication feature enabled, the switch copies the MAC address entries of the
original VLAN to the MAC address table of the marked VLAN. When the switch receives a response
packet from the marked VLAN, it searches the MAC address table of the marked VLAN, obtains the
outbound port for the MAC address of the packet, and unicasts the packet. This feature reduces the
number of broadcasts in the network, as shown in
Figure 1-7.

Likewise, the MAC address entries of the marked VLAN can be copied to the MAC address table of the
original VLAN. When a response packet arrives at the downstream port, the switch determines the
outbound port for the packet by searching the MAC address table of the original VLAN.
