rlOspfRouterLsaChecksum
Module: RADLAN-OSPF-LSDB-MIB
OID (symbolic): RADLAN-OSPF-LSDB-MIB::rlOspfRouterLsaChecksum
OID (numeric): 1.3.6.1.4.1.89.221.1.1.8
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 rlOspfRouterLsaChecksum?
The Fletcher checksum covering this Router LSA's contents, excluding the age field so the age can tick upward without invalidating the checksum. A checksum mismatch during LSDB comparisons flags a corrupted advertisement.
Examples
