The if-match interface command creates a matching rule based on the outbound interface.
The undo if-match interface command deletes the matching rule based on the specified outbound interface.
By default, no matching rule based on the outbound interface is configured.
if-match interface { interface-type interface-number } &<1-16>
undo if-match interface [ interface-type interface-number ] &<1-16>
| Parameter | Description | Value |
|---|---|---|
| interface-type interface-number | Specifies the type and number of the outbound interface. A maximum of 16 outbound interfaces can be specified in the if-match interface command. | - |
Usage Scenario
The if-match interface command is used to filter routes based on the outbound interfaces.
A maximum of 16 outbound interfaces can be configured in this command.
If a node contains multiple if-match interface clauses, the relationship between the if-match interface clauses is OR. If a node contains both if-match interface clauses and other if-match clauses with different matching rules, the relationship between the if-match interface clauses and other if-match clauses is AND. For example, if a node contains if-match interface GE0/0/1, if-match interface GE0/0/2, and if-match acl 2000 clauses, if-match interface GE0/0/1 and if-match interface GE0/0/2 are ORed, whereas if-match interface GE0/0/1 and if-match acl 2000 are ANDed.
Prerequisites
The if-match interface command can be used only after the route-policy command is used.
Precautions
The routing policy matches routes based on outbound interface information. Routes that match the outbound interface information will be checked by other if-match clauses of this node. Routes that do not match the outbound interface information will be checked by the next node.
