| The following scenario
shows that router C uses the gateway of last resort to reach a
subnet it has no explicit knowledge of. Remember that a nonlocal
domain is a major network address space that the router has no
physical connection to. See the main figure for the network
topology used in this scenario.
In the
output of the show ip route command from router C, you can
see that router C does not have a subnet route to 168.72.6.0 or a
summarized route to the major net 168.72.0.0. (see RouterC#show ip route
168.72.6.0
command output).
In the
output from router C, you can see that router C can ping 168.72.6.1.
(see RouterC#ping
168.72.6.1
command output).
