Errata ID: 1805

Status: Reported
Type: Technical

Section 8 says: 

      The IPv4 home address option described in Section 3.1.1 has been
      assigned value 29.  This option is included in the mobility header
      described in [RFC3775].

      The IPv4 address acknowledgement option described in Section 3.2.1
      has been assigned value 29.  This option is included in the
      mobility header described in [RFC3775].

It should say:

      The IPv4 home address option described in Section 3.1.1 has been
      assigned value 29.  This option is included in the mobility header
      described in [RFC3775].

      The IPv4 address acknowledgement option described in Section 3.2.1
      has been assigned value 30.  This option is included in the
      mobility header described in [RFC3775].

Notes:

There's an error in the IANA section of the RFC: while both the IANA registry <http://www.iana.org/assignments/mobility-parameters/> and the section of the RFC describing the option <http://tools.ietf.org/html/rfc5555#section-3.2.1> have the correct type value for the IPv4 address acknowledgement option, i.e., 30, the IANA section <http://tools.ietf.org/html/rfc5555#section-8> assigns type value 29 to both the IPv4 home address option and IPv4 address acknowledgement option.
