11.1. Requesting Router Behavior

The requesting router creates and transmits a Solicit message as described in sections 17.1.1, "Creation of Solicit Messages" and 17.1.2, "Transmission of Solicit Messages" of RFC 3315. The requesting router creates an IA_PD and assigns it an IAID. The requesting router MUST include the IA_PD option in the Solicit message.

The requesting router processes any received Advertise messages as described in section 17.1.3, "Receipt of Advertise Messages" of RFC 3315. The requesting router MAY choose to consider the presence of advertised prefixes in its decision about which delegating router to respond to.

The requesting router MUST ignore any Advertise message that includes a Status Code option containing the value NoPrefixAvail, with the exception that the requesting router MAY display the associated status message to the user.
