At least one MIB declaration places this object in a table row. A value belongs to a row instance; its suffix depends on the row's INDEX or AUGMENTS definition. The index encoding is not inferred here.
Published row index: agentOspfAsLsdbType, agentOspfAsLsdbLsid, agentOspfAsLsdbRouterId.

DESCRIPTION
"The sequence number field is a signed 32-bit
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.
It is used to detect old and duplicate link state
advertisements. The space of sequence numbers is linearly
ordered. The larger the sequence number the more recent
the advertisement."
