hwOspfv3AreaLsdbChecksum
Module: HUAWEI-OSPFV3-MIB
OID (symbolic): HUAWEI-OSPFV3-MIB::hwOspfv3AreaLsdbChecksum
OID (numeric): 1.3.6.1.4.1.2011.5.25.147.1.4.1.7
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 connectionless datagrams; it is commonly referred to as the Fletcher checksum.
What is hwOspfv3AreaLsdbChecksum?
A read-only Fletcher checksum over the complete contents of an Area-Scope LSA, excluding the age field so the age can be incremented independently. It's used the same way as for AS-scope LSAs: to detect corruption or database mismatches between routers.
Examples
