Router is a layer 3 device and it send packets to the clients. best example for this is internet connection. ISP(internet service providers)send packets to their customers through this Router.
Router is a network layer device normaly used to connect different networks. These are two types Software and Hardware routers Cisco 2500 as example of hardware routers but a system running win2000 or win2003 with 2 nic cards can be made as software routers. Hardware routers are normally connected between networks separated geographically.
Routers maintain a routing table having info about network address subnet mask interface and a number field called metric value. After checking ip adddress o f every packet coming it determines the best path and forwards the packet to the other neighbouring router. It works this way.
Router belongs to Network Layer The Main function of Router is to connect two different networks. Router transfers data using the routed protocols like RIP IGRP EIGRP OSPF. Each of them have Administrative distance through which data transfer takes place. Router chooses the shortest path and transfers.
Router is layer 3 device. It's working on network layer. Router connect two different network. Router by default break up broadcast domain. Router forward packet from one network to another network.
1. router is layer 3 device. 2. it's working on netwrk layer. 2. router forword packet from one network to another n/w. 3. router by default break up broadcast domain & collision domain. 4. router will be transmitted packets via best avilable route. 5. router reduce network traffice in networking. 6. router filter unwanted packet in internetwork.
