rlOspfAsbLnkChecksum
Module: CISCOSB-IpRouter
OID (symbolic): CISCOSB-IpRouter::rlOspfAsbLnkChecksum
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.14.7.1.6
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 rlOspfAsbLnkChecksum?
This read-only Integer32 is the Fletcher checksum computed over the ASBR-Summary-LSA's contents, excluding the age field. A checksum failure here flags corrupted data describing reachability to the AS Boundary Router. For example, a bad checksum on this entry would signal potentially corrupted routing information about how to reach the ASBR, which could cause external routes through it to be miscalculated.
