wfOspfLsdbSequence
Module: Wellfleet-OSPF-MIB
OID (symbolic): Wellfleet-OSPF-MIB::wfOspfLsdbSequence

Description: -- 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. 'The sequence number field is a signed 32-bit integer. 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.' REFERENCE 'OSPF Version 2, Section 12.1.6 LS sequence number'
What is wfOspfLsdbSequence?
The signed 32-bit sequence number stamped on this LSA, used by OSPF to distinguish newer advertisements from older or duplicate ones -- a higher sequence number means a more recent version of the LSA. Because the numbering starts near the negative end of the 32-bit range, a 'typical' sequence number often looks like a large negative integer rather than a small positive one.
