Assume that subnets of network 10.0.0.0 are in the IP routing table in a router but that no other network and subnets are known, except that there is also a default route (0.0.0.0) in the routing table. A packet destined for 126.96.36.199 arrives at the router. What configuration command determines whether the default route is used in this case?
The packet is routed using the default route, regardless of other configuration commands. In this scenario, in which the Class A, B, or C network is known, there is no match for the destination in the known subnets, and as a default exists, so the default must be used.
