ARP (Address Resolution Protocol) Table Configuration

ARP Overview

IP logical network addresses are independent of physical addresses. Since the physical address must be used to convey data in the form of a frame from one device to another, a mechanism is required to acquire a destination device hardware address from its IP address. This mechanism/ability is called ARP (Address Resolution Protocol).

The following mechanism describes how a station builds an ARP Table:

Figure 12.2 Building an ARP Table

Station 1 sends ARP Request

Broadcast, specifying IP address of

Station 2

Station 2 receives the broadcast

and identifies its IP address

Station 2 sends an ARP Reply to

Station 1 containing Station 2 MAC

Address

Station 2 updates its ARP table

with the Station 1 address mapping

Station 1 receives the ARP Reply

Station 1 updates its ARP table

with the Station 2 address mapping
