Examine the DHCP configuration between R2 and R3; R2 is configured as the DHCP server and R3 as the client. What is the reason R3 is not receiving the IP address via DHCP?
- A. On R2, the network statement in the DHCP pool configuration is incorrectly configured.
- B. On R3, DHCP is not enabled on the interface that is connected to R2.
- C. On R2, the interface that is connected to R3 is in shutdown condition.
- D. On R3, the interface that is connected to R2 is in shutdown condition.
First we should check which interface on R3 that is connected to R2 via the “show run” command.
From the description we learn interface E0/1 is connected to R2. Use the “show ip interface brief” command to verify the IP address of this interface.
Therefore, we can conclude this interface does not have any IP address and there is no configuration on this interface (except the “description Link to R2” line).
If R3 wants to receive an IP address from R2 via DHCP, interface E0/1 should be configured with the command “ip address dhcp” so the answer “DHCP is not enabled on this interface” is correct.
