Document Summary
What you would find in a routing table: A unicast address (not default gateway, this is for hosts) Metric/cost used to determine a better route measured through. Bandwidth, q. o. s, logical distance (a hop), and congestion. Administrative distance numeric value that represents the quality of the source of information. We assign a cost value to each source of information that can fill our routing table. We look at administrative distance before we look at the metric, if there two entries from the same source. Routing protocol ( s- static, c-connected , o-ospf) Static routes ( manually entered routes ) Dynamic routes ( uses routing protocols: interior routing protocols: Connected routes (routes made by connected interfaces ) Autonomous system (a. s. ) group of networks managed and maintained by the same group of individuals. All networks are assumed to be managed in the same way. All of seneca networks would be one a. s. When you connect multiple a. s. you get the internet.
