The command that instructs the PPPoE (Point-to-Point Protocol over Ethernet) dialer interface to learn its IP address from the server is "ip address negotiated". This command enables the interface to request and automatically obtain an IP address from the PPPoE server during the negotiation process.

When a PPPoE client initiates a connection, it communicates with the server to negotiate various parameters, including its IP address. By using the "ip address negotiated" command, the interface is configured to accept an IP address assigned by the server rather than using a static IP address. This dynamic assignment is especially useful in scenarios where IP address management is handled by the server, allowing for flexibility and efficient use of IP addresses in a network environment.

The other options do not provide the correct mechanism for this function. "ip learn" and "address auto" are not valid commands in the context of PPPoE configurations, while "ip auto-configure" is more relevant to other IP configuration protocols like DHCP, rather than directly applicable to PPPoE.
