Switch 7700 Configuration Guide

102 CHAPTER 5: ROUTING PROTOCOL OPERATION
By default, no matching is performed.
Note that:
■ The if-match clauses for a node in the route policy require that the route
satisfy all the clauses to match the node before the actions specified by the
apply clauses can be executed.
■ If no if-match clauses are specified, all the routes pass the filtering on the
node.
Define Apply Clauses for a Route Policy
The apply clauses specify actions, which are the configuration commands
executed after a route satisfies the filtering conditions that are specified in the
if-match clauses. In this way, some attributes of the route can be modified.
Perform the following configurations in Route policy view.
Match the tag domain of the
OSPF routing information
if-match tag value
Cancel the tag domain of the
matched OSPF routing
information
undo if-match tag
