The AFI Flags field is defined in <xref target="IANA"/>
Currently, the two low order bits MUST always be set, i.e. 1,
and the rest unset, i.e. 0. This allows the router to prepare
for less change should the AFIs be separated in a future
version. This field is likely to be removed before
publication.
