Usage Guidelines

Usage Scenario

You can run the if-match tag command to filter OSPF or IS-IS routes based on the tags.

For the same node in a route-policy, the relationship between the if-match clauses is "AND". The route must meet all the matching rules before the actions defined by the apply clauses are performed. If no if-match clause is specified, all the routes are matched.

Prerequisites

The if-match tag command can be used only after the route-policy command is used to enter the route-policy view.

Example

# Define a rule to match routes with the tag value 8.

<sysname> system-view

[sysname] route-policy policy permit node 10

[sysname-route-policy] if-match tag 8
