nsVrOspfLsdbChecksum
Module: NETSCREEN-VR-OSPF-MIB
OID (symbolic): NETSCREEN-VR-OSPF-MIB::nsVrOspfLsdbChecksum
OID (numeric): 1.3.6.1.4.1.3224.18.5.4.1.7
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 connec- tionless datagrams; it is commonly referred to as the Fletcher checksum.
What is nsVrOspfLsdbChecksum?
The Fletcher checksum of the LSA's full contents excluding the age field (so the age can tick up without invalidating the checksum). It's used internally to detect corruption in flooded LSAs rather than something an admin reads directly.
Examples
