Using the Ethernet Frame to Deliver the Packet to the Default Router

In this figure, the Ethernet switch happens to have already learned its entries for Hannah's (0200.1111.1111) and R1's (0200.3333.3333) Ethernet MAC addresses. With a destination address of 0200.3333.3333, the switch simply looks at the frame and decides to send the frame out its E2 interface. The frame, which, of course, has the IP packet in it, is delivered to R1. Finally, the packet has made it to the default router. The router will know to process the incoming frame because the destination Ethernet address is its own address.
