Abstract:
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.
