Routers and Layer 3 Switching. While most switches operate at the Data layer (Layer 2) of the OSI Reference Model, some incorporate features of a router and operate at the Network layer (Layer 3) as well. In fact, a Layer 3 switch is incredibly similar to a router.
So when a packet arrive at a Router, Which is a Layer 3 device, it will route the packet on bases of the IP address (Layer 3). But when the packet traverses the network, it needs to be also identified with the Layer 2 Address. For this purpose a Router also needs to do an ARP lookup and has an ARP table. Although a Router is a Layer 3 (IP) Device, it will change the Layer 2 (MAC) Source and Destination MAC address!!! Like Show 1 Like (1)
