Usage Scenario

If no source IP address is specified, the client uses the source IP address that the router specifies to send packets. The source IP address must be configured for an interface with stable performance. The loopback interface is recommended. Using the loopback interface as the source interface simplifies the ACL rule and security policy configuration. This shields the IP address differences and interface status impact, and incoming and filters outgoing packets, and implements security authentication.

Precautions

The tftp command also configures the source IP address whose priority is higher than that of the source IP address specified in the tftp client-source command. If you specify source addresses in the tftp client-source and tftp commands, the source IP address specified in the tftp command is used for data communication. The source address specified in the tftp client-source command applies to all TFTP connections. The source address specified in the tftp command applies only to the current TFTP connection.
