This is an example of the output when the packet coming in on port 1 in VLAN 5 is sent to an address
already learned on the VLAN on another port. It should be forwarded from the port on which the address
was learned.

This is an example of the output when the packet coming in on port 1 in VLAN 5 has a destination MAC
address set to the router MAC address in VLAN 5 and the destination IP address unknown. Because there
is no default route set, the packet should be dropped.

This is an example of the output when the packet coming in on port 1 in VLAN 5 has a destination MAC
address set to the router MAC address in VLAN 5 and the destination IP address set to an IP address that
is in the IP routing table. It should be forwarded as specified in the routing table.
