Detailed explanation-1: -Layer 3 is the network layer. This is where we send information between and across networks through the use of routers. Instead of just node-to-node communication, we can now do network-to-network communication. Routers are the workhorse of Layer 3-we couldn’t have Layer 3 without them.
Detailed explanation-2: -A router is a commonly utilised Layer 3 device. Operating at Layer 3, a router will inspect the IP and IPX addresses of incoming data packets.
Detailed explanation-3: -Layer 3 switch is also called multilayer switch. It is a specialized hardware device used in network routing, which is conceived as a technology to improve network routing performance on large local area networks (LANs) like corporate intranets. A Layer 3 switch is both a switch and a router.
Detailed explanation-4: -The most common Layer 3 device used in a network is the router. A router is able to look into the Layer 3 portion of traffic passing through it (the source and destination IP addresses) to decide how it should pass that traffic along.
