Usage Guidelines
Usage Scenario
You can run the if-match route-type command to filter OSPF or IS-IS routes based on the route type.
Multiple if-match route-type clauses can be specified. The relationship between if-match route-type clauses is "OR". The relationship between if-match clauses is "AND".
Prerequisites
The if-match route-type command can be used only after the route-policy command is used.
Precautions
The routing policy matches routes based on the route type. Routes that match the route type will be checked by other if-match clauses of this node. Routes that do not match the route type will be checked by the next node.
For the same node in a routing policy, if two if-match route-type clauses are the same, the latter if-match route-type will not override the previous if-match route-type. After the latter clause is configured, both clauses take effect simultaneously. The relationship between if-match route-type clauses is "OR". That is, the actions defined by apply clauses can be performed on a route as long as the route meets one of the matching rules. For example, if both the if-match route-type is-is-level-1 and if-match route-type external-type1or2 commands are configured on the same node of a route policy, both IS-IS Level-1 routes and OSPF external routes can match the route policy.
external-type1or2 refers to external-type1 or external-type2. For the same node in a route policy, configuring both the if-match route-type external-type1 and if-match route-type external-type2 is equivalent to configuring the if-match route-type external-type1or2 command. The two operations generate the same configuration file.
Similarly, nssa-external-type1or2 refers to nssa-external-type1 or nssa-external-type2. For the same node in a route policy, configuring both the if-match route-type nssa-external-type1 and if-match route-type nssa-external-type2 commands is equivalent to configuring the if-match route-type nssa-external-type1or2 command. The two operations generate the same configuration file.
