rlOspfSumLnkChecksum
Module: CISCOSB-IpRouter
OID (symbolic): CISCOSB-IpRouter::rlOspfSumLnkChecksum
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.14.6.1.6
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 connectionless datagrams; it is commonly referred to as the Fletcher checksum.
What is rlOspfSumLnkChecksum?
This read-only Integer32 is the Fletcher checksum over the Summary-LSA's contents, excluding the age field so it survives normal aging. A mismatched checksum flags a corrupted or tampered copy of the inter-area summary route information. For example, a checksum failure on a Summary-LSA advertising a remote-area subnet would flag corrupted data that could cause that inter-area route to be miscalculated.
