![]() ![]() When it finds the matching MAC address and associated switch port and then forwards the frame out the correct port to get to the destination MAC address. R1 sends a packet with the destination IP and MAC address of R2, when the local switch receives the frame, it looks at the destination MAC address and looks up the MAC address in the cam table (also known as mac-address table). Now R1 knows the destination MAC address to use in the frame(s) when sending traffic destined to 10.1.1.2 R1 will first send an ARP request thus requesting the MAC address of R2’s IP address (10.1.1.2/24) and once it receives a reply the information will be placed into R1’s ARP table. Lets say for example R1 needs to communicate with R2. In order to ensure layer three to layer two communication, a switch or router needs to have an ARP table, this table is a local table that contains ip addresses and their matching associated MAC addresses.
