The concept of VLAN is to split the broadcast domain: so, in this section, we will see how broadcasts are handled in a VLAN environment using the simulation mode. Use the same InterVLAN topology we used previously. From PC0 ping to 255.255.255.255, this sets the destination MAC address to FFFF.FFFF.FFFF, which is the layer 2 broadcast address. Switch to the simulation mode and see what happens. The switch receives an ICMP packet from PC0, and sends out two copies of it: one to the router and another to PC1. If this network weren't divided into VLANs, the ICMP packet would've been sent to each and every PC connected to the switch.
