Module: CISCOSB-IpRouter
OID (symbolic): CISCOSB-IpRouter::rlOspfNetLnkSequence
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.14.5.1.5
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 rlOspfNetLnkSequence?
This read-only value reports the signed 32-bit sequence number of a network-LSA, used to detect old and duplicate advertisements, where a larger number means a more recent advertisement. An admin compares this across polls to confirm whether the network-LSA data being viewed is the latest version rather than a stale duplicate. For example, seeing this sequence number unchanged across two OSPF SPF recalculations confirms the designated router hasn't re-originated this network-LSA in between.
