intelligent-convergence enable

Function

The intelligent-convergence enable command enables IS-IS intelligent convergence.

The undo intelligent-convergence enable command disables IS-IS intelligent convergence.

By default, IS-IS intelligent convergence is disabled.

Usage Guidelines

Usage Scenario

In a fault-triggered switching scenario where the local device receives a route from a single node, to enable IS-IS intelligent convergence, run the intelligent-convergence enable command. After this command is run, IS-IS can perform fast route convergence by using the fast convergence algorithm, thereby improving convergence performance.

Precautions

In the same networking scenario, the convergence speeds of devices with the intelligent-convergence enable command configuration increase significantly, far higher than those of the devices without this command configuration. As a result, routing loops may occur. Therefore, exercise caution when you run this command.

Example

# Enable IS-IS intelligent convergence.
