NOTE:
•
The if-match clauses of a routing policy node are in logic AND relationship. Routing information has to
satisfy all its if-match clauses before being executed with its apply clauses. If an if-match command
exceeds the maximum length, multiple idendical if-match clauses are generated. These clauses are in
logical OR relationship. Routing information only needs to match one of them.
• You can specify any number of if-match clauses for a routing policy node. If no if-match clause is
specified, and the routing policy node is in permit mode, all routing information can pass the node. If it
is in deny mode, no routing information can pass it.
• If the ACL referenced by an if-match clause does not exist, the clause is always satisfied; if no rules of the
referenced ACL are matched or the matching rule is inactive, the clause is not satisfied.
• An ACL specified in an if-match clause should be a non-VPN ACL.
• The if-match commands for matching IPv4 destination, next hop and source address are different from
those for matching IPv6 ones.
• BGP does not support criteria for matching against outbound interfaces of routing information.
Defining apply clauses
