of the LS age field is considered the DoNotAge
bit for support of on-demand circuits."

DESCRIPTION
"This field is the checksum of the complete
contents of the advertisement, excepting the
age field. The age field is excepted so that
an advertisement's age can be incremented
without updating the checksum. The checksum
used is the same that is used for ISO
