ip rarp client

To enable RARP (Reverse Address Resolution Protocol) client, use the command ip rarp client in Global Configuration Mode. The no form of this command disables the RARP client. The RARP resolves an IP address from a given hardware address. The client that requests for the IP is the RARP client. The IP address of the default interface is obtained through RARP, when the IP address configuration mode is dynamic. After finishing the RARP Max retries, IP is obtained through DHCP (Dynamic Host Configuration Protocol).
