rlOspfAseLnkSequence
Module: CISCOSB-IpRouter
OID (symbolic): CISCOSB-IpRouter::rlOspfAseLnkSequence
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.14.8.1.3
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 rlOspfAseLnkSequence?
This read-only Integer32 is the signed sequence number of the AS-External-LSA, letting routers distinguish stale copies from more recent ones. An admin watching this value confirms the redistributing ASBR is actively refreshing the external route rather than leaving a stale entry in place. For example, monitoring this sequence number for an externally redistributed default route confirms whether the ASBR is still actively re-advertising it.
