rlOspfAseLnkChecksum
Module: CISCOSB-IpRouter
OID (symbolic): CISCOSB-IpRouter::rlOspfAseLnkChecksum
OID (numeric): 1.3.6.1.4.1.9.6.1.101.26.14.8.1.5
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 rlOspfAseLnkChecksum?
This read-only Integer32 is the Fletcher checksum over the AS-External-LSA's contents, excluding the age field. A checksum mismatch flags corrupted redistributed route information before it gets installed into the routing table. For example, a bad checksum on an AS-External-LSA would indicate the redistributed route's data was corrupted before other routers could safely install it.
