[CAUSE] The tmnxIsisCorruptRemainingLifetime notification is sent when an LSP is received with a possible corrupt Remaining Lifetime field. The Remaining Lifetime of a received LSP is considered as possible corrupt based on following algorithm: - The LSP has passed all acceptance tests. - The LSP is newer than the copy in the local LSPDB or no copy present. - The Remaining Lifetime in the received LSP is less than Zero Age Lifetime. - The adjacency to the neighbor from which the LSP is received has been up for a minimum of Zero Age Lifetime. [EFFECT] It is possible that an LSP is purged prematurely. [RECOVERY] The ISIS system will try to recover by setting the Remaining Lifetime to the tmnxIsisLspMinRemainingLifetime value.
