Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: 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.
What is rlOspfRtrLnkSequence?
This read-only value reports the signed 32-bit sequence number of a router-LSA, used to detect old and duplicate advertisements, where a larger number indicates a more recent advertisement. An admin compares this across observations to confirm whether the LSA data being viewed is the latest version or a stale duplicate. For example, seeing this sequence number increase between two SNMP polls confirms the router has issued a newer version of this LSA since the last check.
