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.
What is agentOspfAreaOpaqueLsdbSequence?
Reports the signed 32-bit LS sequence number of this area-scoped Opaque LSA, starting near -0x7FFFFFFF and increasing over the LSA's lifetime; a higher value means a more recent instance. Used by OSPF (and admins inspecting the LSDB) to detect stale or duplicate copies of the same LSA.
