The main purpose of a routing table is to help routers make effective routing decisions. Whenever a packet is sent through a router to be forwarded to a host on another network, the router consults the routing table to find the IP address of the destination device and the best path to re...
The router reads a packet's header to determine where it is going, then consults the routing table to figure out the most efficient path to that destination. It then forwards the packet to the next network in the path. To learn more about IP routing and the protocols that are used ...
A routing table records the paths that packets should take to reach every destination that the router is responsible for. Think of train timetables, which train passengers consult to decide which train to catch. Routing tables are like that, but for network paths rather than trains. Routers ...
A routing table is a type of data file that acts as a map and is often installed on a router, networked computer or other hardware. The routing table contains information about various routes between devices in order to present the most efficient paths for data packets. Advertisements Techopedia...
This type is typically used with a stub router, which is a router that has only one route to reach all other networks. Dynamic routing: Adjustments of the routes are automatically made according to the current state of the route in the routing table. Dynamic routing uses protocols to ...
A router checks its routing table to find the IP address of the destination machine when a data packet is sent to another host. Each routing table may vary in terms of its information. But all routing tables include a destination, subnet mask, gateway, interface, and routes. ...

Generally, a router is connected to multiple data lines, and when a router receives inbound data, it reads the header of the data packet. This contains the ultimate destination of the data, and then using a routing table, calculates the best route for the packet to take based on the ...
Enhanced Interior Gateway Routing Protocol.EIGRP evolved from IGRP. If a router can't find a route to a destination in one of these tables, it queries nearby routers, which then query routers closer to them until a route is found. When a routing table entry changes in one of the routers...
