| Router(config)# interface fastethernet 0/0 | Enters interface configuration mode for the specified interface. |
| Router(config-if)# ip helper-address ip-address | Specifies the IP address for any TFTP and/or DNS servers. |
| | NOTE: A separate ip helper-address command is required for each server if the servers are on different hosts. You configure multiple TFTP server targets by using the ip helper-address commands for multiple servers. |
