The if-match cost command sets a matching rule that is based on the route cost.
The undo if-match cost command cancels the configuration.
By default, no matching rule based on the route cost is set.

if-match cost { greater-equal greater-equal-value [ less-equal less-equal-value ] | less-equal less-equal-value }
| Parameter | Description | Value |
|---|---|---|
| cost | Specifies the route cost. | The value is an integer ranging from 0 to 4294967295. |
| greater-equal greater-equal-value | Specifies the minimum value of route cost. | The value is an integer ranging from 0 to 4294967294. |
| less-equal less-equal-value | Specifies the maximum value of route cost. less-equal-value is demanded to be greater than greater-equal-value. | The value is an integer ranging from 1 to 4294967295. |
Usage Scenario
You can use the if-match cost command to configure a node to filter routes based on the route costs. After such a matching rule is configured, you can apply the apply clauses to change the attributes of the routes that match the matching rule.
Prerequisites
The if-match cost command can be used only after the route-policy command is used.
Configuration Impact
When you filter routes based on the costs, only the routes that meet the filter conditions can match the matching rule.
