1. Figure 7 17 Example of a Network Using ABC 7 30 Note Advanced Concepts Automatic Broadcast Control ABC To learn host D s MAC address host A sends a broadcast ARP request Because the switch does not yet know the location of host D it floods the request out all ports However the switch also learns from the ARP request the location of host A and stores this information in its ARP cache Host D receives the ARP request as will all other hosts connected to the switch and responds with a unicast packet through the switch to host A The switch monitors this response learns the location of host D and stores this informa tion in its ARP cache Thus the switch now knows the address information for both host A and host D Now hosts A and D can send unicast packets to each other because they have learned each other s addresses Suppose that host C now wants to communicate with host A C sends a broadcast ARP request to the switch Because the switch already has A s address information it does not flood C s ARP request out all ports but instead sends a proxy ARP reply to C that tells C the address information for host A Host C can now send unicast packets directly to host A From these packets host A will learn host C s addressing information and be able to respond with unicast packets addressed to host C The result is reduced network traffic because host C s broadcast ARP request was not flooded on the swit
