A network administrator configures the G0/0/0 interface with the ip address 10.1.1.0 255.255.255.0 command. However, when the administrator issues the show ip route command, the routing table does not show the directly connected network. What is the possible cause of the problem?

  • No packets with a destination network of 172.16.1.0 have been sent to R1.
  • The configuration needs to be saved first.
  • The G0/0/0 interface has not been activated.
  • The subnet mask is incorrect for the IPv4 address.

Explanation: A directly connected network will be added to the routing table when these three conditions are met: (1) the interface is configured with a valid IP address; (2) it is activated with the no shutdown command; and (3) it receives a carrier signal from another device that is connected to the interface. An incorrect subnet mask for an IPv4 address will not prevent its appearance in the routing table, although the error may prevent successful communications.
