cospfLocalLsdbChecksum
Module: CISCO-OSPF-MIB
OID (symbolic): CISCO-OSPF-MIB::cospfLocalLsdbChecksum
OID (numeric): 1.3.6.1.4.1.9.10.99.7.1.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This field is the checksum of the complete contents of the advertisement, excepting the age field. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connectionless datagrams; it is commonly referred to as the Fletcher checksum.
What is cospfLocalLsdbChecksum?
This object reports the Fletcher checksum of a link-local-scope LSA, excluding its age field for the same reason as cospfLsdbChecksum, so the checksum stays stable as the LSA simply ages without real content changes. It matters identically to its non-local counterpart, letting an admin detect corruption or divergence in a link-local LSA between routers sharing that segment without manually diffing the full advertisement payload.
