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 swL3OspfExternalLsdbSequenceNo?

The signed 32-bit LSA sequence number for this external LSA, used the same way as swL3OspfInternalLsdbSequenceNo to detect stale or duplicate copies. Admins check this when comparing two received copies of the same external LSA.

Examples
