The ip route dhcp command configures a routing entry delivered by the DHCP server to a DHCP client.
The undo ip route dhcp command cancels the configuration.
By default, no routing entry is delivered by the DHCP server to a DHCP client.

The ip route dhcp command is used on DHCP clients. After the ip route ip-address { mask | mask-length } interface-type interface-number dhcp [ preference-value ] command is run, a route with the gateway address as the next-hop IP address is automatically generated when a DHCP client obtains an IP address from the DHCP server through a DHCP request.
