Usage guidelines

IS-IS NSR takes effect on a per-process basis. As a best practice, enable NSR for each IS-IS process.

IS-IS NSR and IS-IS GR are mutually exclusive. Therefore, do not configure the non-stop-routing command and the graceful-restart command at the same time.

Examples

# Enable NSR for IS-IS process 1.

<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] non-stop-routing
