Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information IS-IS normally purges LSPs with an incorrect data link checksum causing the LSP source to regenerate the
message. A cycle of purging and regenerating LSPs can occur when a network link continues to deliver accurate
LSPs even though there is a link causing data corruption. This process could cause disruption to your system
operation.

Syntax

Parameters

specify a tag, a null tag is assigned.
Defaults No processes are configured.
Command Modes INTERFACE
