Determining the route administrative distance

Determining the route administrative distance 
9.1.5 A router can discover routes through dynamic routing protocols or routes can be configured manually. After the routes are discovered or configured, the router must choose the best routes to other networks.
The router uses the administrative distance of each route to determine the best path to a particular destination. The administrative distance is a number that measures the trustworthiness of the source of the route information. The lower the administrative distance, the more trustworthy the source.
Different routing protocols have different default administrative distances. The path with the lowest administrative distance is installed in the routing table.
In the Lab Activity, students will analyze two routing protocols.
The next page will discuss route metrics.
