A new version of I-D, draft-decraene-isis-lsp-lifetime-problem-statement-00.txt
has been successfully submitted by Bruno Decraene and posted to the IETF repository.

Revision:	00
Title:		IS-IS LSP lifetime corruption - Problem Statement
Document date:	2015-07-06
Group:		Individual Submission
Pages:		6
URL:            https://www.ietf.org/internet-drafts/draft-decraene-isis-lsp-lifetime-problem-statement-00.txt
Status:         https://datatracker.ietf.org/doc/draft-decraene-isis-lsp-lifetime-problem-statement/
Htmlized:       https://tools.ietf.org/html/draft-decraene-isis-lsp-lifetime-problem-statement-00

   The IS-IS protocol exchanges Link State Packet (LSP) to exchange
   routing information.  The lifetime of this LSP is located in the LSP
   header and is neither protected from corruption by the Fletcher
   checksum nor by cryptographic authentication.  So the LSP lifetime
   may be altered, either accidentally or maliciously any time.

   The lifetime field of the LSP is an important field for the correct
   operation of IS-IS.  Corruption of this LSP lifetime may cause
   flooding storm with severe impact in the network.

   This draft documents the problem statement and calls for a solution.
