Module: COSINE-ORION-MIB
OID (symbolic): COSINE-ORION-MIB::csOspfExternLsaCksumSum
OID (numeric): 1.3.6.1.4.1.3085.3.1.4.2.4.1.1.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The 32-bit unsigned sum of the LS checksums of the external link-state advertisements con- tained in the link-state database. This sum can be used to determine if there has been a change in a router's link state database, and to compare the link-state database of two routers.
What is csOspfExternLsaCksumSum?
This Integer32 is the 32-bit unsigned sum of the LS checksums of all external link-state advertisements in the database, usable to detect a change in the database or compare it against another router's. Because any content change to an external LSA shifts this sum, an admin can use it as a lightweight fingerprint to detect drift between two routers that should see the same external routes. Comparing this value on two area border routers that should be database-synchronized is a quick way to spot a missed LSA.
