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.
What is swL3OspfInternalLsdbSequenceNo?
4-byte signed sequence number used to detect old or duplicate copies of this LSA, with larger values meaning more recent advertisements. An admin compares sequence numbers across LSDB snapshots to confirm whether a router has actually refreshed an LSA or is still advertising a stale one.
