TAILIEUCHUNG - Chapter 21 Network Layer: Address Mapping, Error Reporting, and Multicasting

The delivery of a packet to a host or a router requires two levels of addressing: logical and physical. We need to be able to map a logical address to its corresponding physical address and vice versa. This can be done by using either static or dynamic mapping. | Chapter 21 Network Layer: Address Mapping, Error Reporting, and Multicasting Copyright © The McGraw-Hill Companies, Inc.

We need to be able to map a logical address to its corresponding physical address and vice versa. This can be done by using either static or dynamic mapping. Mapping Logical to Physical Address Mapping Physical to Logical Address Topics discussed in this section: 21. Figure ARP operation 21. Figure ARP packet 21. Figure Encapsulation of ARP packet 21. Figure Four cases using ARP 21. An ARP request is broadcast; an ARP reply is unicast. Note 21. A host with IP address and physical address B2:34:55:10:22:10 has a packet to send to another host with IP address and physical address A4:6E:F4:59:83:AB. The two hosts are on
