Performing the Initial Configuration on the Router
Purpose
Establishes a static route.
Selects a network as a candidate route for computing the
gateway of last resort.
Creates a static route to network 0.0.0.0 0.0.0.0 for
computing the gateway of last resort.
Returns to privileged EXEC mode.
Displays the current routing table information.
Verify that the gateway of last resort is set.
