Setting the Administrative Distance for a Route
The administrative distance is an integer that is associated with each route known
to a router. The distance represents how reliable the source of the route is considered
to be. A lower value is preferred over a higher value. An administrative distance of
255 indicates no confidence in the source; routes with this distance are not installed
in the routing table.
Table 5 on page 27 lists the default distance for each type of source from which a
route can be learned.
