Module: CISCO-OSPF-MIB
OID (symbolic): CISCO-OSPF-MIB::cospfIfLsaCksumSum
OID (numeric): 1.3.6.1.4.1.9.10.99.4.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The 32-bit unsigned sum of the link-state advertisements' LS checksums contained in this interface's link-local link state database. The sum can be used to determine if there has been a change in the interface's link state database, and to compare the interface link-state database of routers attached to the same subnet.
What is cospfIfLsaCksumSum?
This object reports the checksum sum across the link-local LSAs on this specific OSPF interface's link-local database, explicitly usable per the description to detect a database change and to compare consistency with other routers attached to the same subnet. It matters for pinpointing a link-local LSA sync issue down to a single shared segment, the tightest scope of database comparison available in this MIB family. If routers on the same physical subnet report different values here, that is a very localized flooding or adjacency problem specific to that link, distinct from any area- or AS-wide LSDB issue.
