| scale | to alter to a certain size; referst to routing tables that grow according to the addition of new networks |
| algorithm | well-defined rule or process for arriving at a solution to a problem |
| autonomous system | a collection of networks under a common administration sharing a common routing strategy |
| routing domain | subdivided by areas; the same as an autonomous system |
| interior gateway protocols | used to exchange routing information within an autonomous system |
| exterior gateway protocols | used to route between autonomous systems |
| path vector protocol | marks and shows the path that update information takes as it diffuses through the network |
| distance vector | class of routing algorithms that iterate on the number of hops in a route to find a shortest-path spanning tree |
| vector | a quantity characterized by a magnitude and direction |
| link-state | the status of a link, including the interface IP address and subnet mask |
| link-state router | a router that uses a link-state routing protocol |
| converged | when all intermediate devices have the same consistent network topology in their routing tables |
