6.8 ICMP Mobile Prefix Advertisement Message Format
(snip)
The Mobile Prefix Advertisement messages may have options. These
options MUST use the option format defined in RFC 2461 [12]. This
document defines one option which may be carried in a Mobile Prefix
Advertisement message, but future documents may define new options.
Mobile nodes MUST silently ignore any options they do not recognize
and continue processing the message.
Prefix Information
Each message contains one or more Prefix Information options.
Each option carries the prefix(es) that the mobile node should use
to configure its home address(es). Section 10.6 describes which
prefixes should be advertised to the mobile node.
The Prefix Information option is defined in Section 4.6.2 of RFC
2461 [12], with modifications defined in Section 7.2 of this
specification. The home agent MUST use this modified Prefix
Information option to send home network prefixes as defined in
Section 10.6.1.
If the Advertisement is sent in response to a Mobile Prefix
Solicitation, the home agent MUST copy the Identifier value from that
message into the Identifier field of the Advertisement.
