Usage Guidelines

Usage Scenario

A large number of external routes can be imported to IS-IS, which causes extra burdens on IS-IS-enabled devices. To solve this problem, run the apply isis command to set the level of the routes to be imported to IS-IS.

Prerequisites

The apply isis command can be used only after the route-policy command is used.

Precautions

When a routing policy takes effect, it affects route receiving and advertising in IS-IS.

Example

# Set the level of the routes imported to IS-IS.
