csOspfExtLsdbChecksum

Module: COSINE-ORION-MIB

OID (symbolic): COSINE-ORION-MIB::csOspfExtLsdbChecksum

OID (numeric): 1.3.6.1.4.1.3085.3.1.4.2.4.1.11.1.6

Node type: OBJECT-TYPE

Type: Integer32

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 connec- tionless datagrams; it is commonly referred to as the Fletcher checksum.

What is csOspfExtLsdbChecksum?

This Integer32 is the checksum, the same Fletcher checksum used for ISO connectionless datagrams, of the complete external LSA contents excluding the age field. An admin comparing this checksum for the same external route as seen by two different routers can quickly detect content divergence without decoding the full advertisement. A mismatch here between two routers that should both have received the identical external LSA points to a database synchronization issue.

Examples
