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 hm2AgentOspfAreaOpaqueLsdbSequence?

Signed 32-bit sequence number of this area-scoped opaque LSA, starting at 80000001 hex; larger means more recent, so it is used to spot old or duplicate advertisements.
