Administrationsafstande

Administrationsafstande, also known as administrative distances, are numerical values used in routing protocols to determine the trustworthiness of routing information received from different sources. These values range from 0 to 255, with lower values indicating more trustworthy routes. The concept of administrative distances is crucial in network routing, as it helps routers make decisions about which routes to prefer when multiple paths to the same destination are available.

In the context of the Border Gateway Protocol (BGP), administrative distances are used to prioritize routes learned from different sources. For example, BGP routes typically have an administrative distance of 20, while routes learned from the Interior Gateway Routing Protocol (IGRP) have an administrative distance of 100. This means that BGP routes are preferred over IGRP routes when both are available.

Administrative distances can also be manually configured by network administrators to influence the routing decisions made by routers. For instance, an administrator might set a lower administrative distance for routes learned from a specific source to ensure that these routes are preferred over others.

In summary, administrationsafstande are essential in network routing as they provide a mechanism for routers to evaluate and prioritize routing information from different sources. By assigning numerical values to routes based on their trustworthiness, routers can make informed decisions about the best paths to use for forwarding traffic.
