Chapter 4 Initial Configuration
Performing the Initial Configuration on the Router
If the router has no interface on the default network, but does have a route to it, it considers this network
as a candidate default path. The route candidates are examined and the best one is chosen, based on
administrative distance and metric. The gateway to the best default path becomes the gateway of last
resort.
