An administrator has configured a DHCPv4 relay router and issued these commands:
Router(config)# interface g0/0
Router(config-if)# ip address 10.0.1.1 255.255.255.0
Router(config-if)# no shutdown
Router(config-if)# exit
Router(config)# ip dhcp pool RELAY
Router(dhcp-config)# end
The clients are not receiving IP parameters from the DHCPv4 server. What is a possible cause?
- The pool cannot be named ‘RELAY’.
- The router is configured as a DHCPv4 client.
- The IP address is incorrect for the subnet mask that is used.
- The ip helper-address command is missing.
Answers Explanation & Hints: This router should be configured with the ip helper-address command, followed with the IP address of the DHCPv4 server, because the router is meant to be used as a relay agent. The ip dhcp pool RELAY command just names the DHCPv4 pool, and it does not enable the relay function.
