Module: CISCO-OSPF-MIB
OID (symbolic): CISCO-OSPF-MIB::cospfOpaqueAreaLsaCksumSum
OID (numeric): 1.3.6.1.4.1.9.10.99.2.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The 32-bit unsigned sum of the Opaque Area and AS link-state advertisements' LS checksums contained link state database of this area. The sum can be used to determine if there has been a change in the link state database for Opaque Area and AS link-state advertisements
What is cospfOpaqueAreaLsaCksumSum?
This object reports the checksum sum across Opaque Area and AS LSAs visible within this specific area, the area-scoped counterpart to cospfOpaqueASLsaCksumSum, explicitly usable to detect a change in that area's Opaque LSA set. This has the same operational value as its AS-wide counterpart but scoped down; an admin comparing this value between all routers in one specific area can pinpoint an LSA database divergence localized to that area, rather than a broader domain-wide issue.
