Usage Guidelines

Usage Scenario

To change the cost of routes for selecting the optimal route, you can apply a routing policy containing the apply cost command.

Prerequisites

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

Precautions

When a routing policy takes effect, it affects route selection.

The costs of imported routes are independent of the routing policy after the undo apply cost command is used to cancel the configuration of route costs.

Example

# Define an apply clause to set the route cost to 120.

<HUAWEI> system-view

[~HUAWEI] route-policy policy permit node 10

[*HUAWEI-route-policy] apply cost 120
