This object reports the sequence number of a specific link-local-scope link-state advertisement, functioning identically to cospfLsdbSequence but for LSAs that do not flood beyond the local link or subnet, since this MIB's local LSDB tables generally hold these link-local-scope entries. It matters for the same reason, a higher sequence number means a more recent version of that link-local advertisement, but comparing it is only meaningful between routers attached to the same specific segment, since link-local LSAs are not visible beyond that scope. An admin comparing this value between two routers on the same shared subnet expects a match if both hold the current version of that link-local LSA.
