node and will not match against the next policy node. If not, the packet will match against the next policy node.

permit: Specifies the match mode of the policy node as permit. If a packet satisfies all the rules defined by the if-matchclauses, the apply clauses are executed. If not, the packet will match against the next policy node.

node node-number: Number of the IPv6 policy node, in the range 0 to 65535. Packets will match against the node with a smaller node-numberfirst.

Description Use the ipv6 policy-based-routecommand to create an IPv6 policy or policy node and enter IPv6 policy routing view.

Use the undo ipv6 policy-based-routecommand to remove an IPv6 policy or policy node.

No IPv6 policy or policy node is created by default.

An IPv6 policy may consist of several nodes, and a node consists of if-matchclauses and apply clauses. The if-matchclauses define the match rules for the node and the apply clauses define the actions that should be taken for matched packets.

Note that:

■There is an AND relationship between the if-matchclauses of a node. That is to say, a packet must satisfy all matching rules specified by all if match clauses for the node before the action specified by the apply clause is taken.

■There is an OR relationship between nodes of the policy. That is, if a packet passes a node, it passes the policy.

■A packet passing a node of a policy will not go to the next node of the policy for a match.

■A packet not passing any node of a policy cannot pass the policy. It will be routed through the routing table.

■If multiple nodes are defined for a policy, the match mode of at least one node must be permit.
