"The 32 bit identifier for the Stub Area. On
creation, this can be derived from the in-
stance."

ospfLsdbLsid OBJECT-TYPE
SYNTAX IpAddress

DESCRIPTION
"The Link State ID is an LS Type Specific field
containing either a Router ID or an IP Address;
it identifies the piece of the routing domain
that is being described by the advertisement."

-- Note that the OSPF Sequence Number is a 32 bit signed
-- integer. It starts with the value '80000001'h,
-- or -'7FFFFFFF'h, and increments until '7FFFFFFF'h
-- Thus, a typical sequence number will be very negative.
ospfLsdbSequence OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The sequence number field is a signed 32-bit
integer. It is used to detect old and dupli-
cate link state advertisements. The space of
sequence numbers is linearly ordered. The
larger the sequence number the more recent the
advertisement."

ospfLsdbChecksum OBJECT-TYPE
SYNTAX Integer32
MAX-ACCESS read-only
STATUS current
Baker & Coltun Standards Track [Page 26]
RFC 1850 OSPF MIB November 1995
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 connec-
tionless datagrams; it is commonly referred to
as the Fletcher checksum."
