The packet, which is sent, is encapsulated in an ethernet frame which would contain the
source mac-address as the systems (192.1681.3) mac-address and the destination mac-
address as the routers interface (192.168.1.2) mac-address, as packets bound for a different
network is sent to the router. When the packet reaches the switch port, which is connected
to the 192.168.1.3 system, the switch looks into the destination mac-address in the frame.
The switch does not look into the IP packet, as it does not have the capacity to perform the
same. After understanding the mac-address, it checks in it’s mac-address table for a match.
After identifying the port number on which the router is connected, the frame
encapsulating the packet is forwarded to the appropriate port and further processed by the
