Routing table

Meaning in networking & telecommunications, with examples

How it is used

Engineers check or display the routing table when traffic doesn't arrive: 'Is the route in the routing table?' A route can be missing from, added to or removed from the table. The default route is used when no more specific route matches.

Example sentences

  1. The 10.30.0.0/16 network isn't in the routing table, so the router drops that traffic.

  2. After the OSPF change, the routing table on the core router has twice as many entries.

  • routingThe process of choosing the path that traffic takes from one network to another, carried out by routers using routes that are either entered by hand or learned from other routers.
  • static routeA route that an engineer enters into a router by hand, telling it exactly where to send traffic for a particular network, instead of letting a routing protocol learn it.
  • routerA device that connects different networks and decides, packet by packet, the best path for data to reach its destination, usually based on IP addresses.
  • default gatewayThe router address that a device sends traffic to when the destination is outside its own subnet; without it, a device can only talk to its local network.
