898 CHAPTER 69: IPV6 UNICAST POLICY ROUTING CONFIGURATION COMMANDS
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-match clauses, 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-number first.
Description Use the
ipv6 policy-based-route command to create an IPv6 policy or policy
node and enter IPv6 policy routing view.
Use the
undo ipv6 policy-based-route command 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-match
clauses and apply clauses. The if-match clauses 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-match clauses 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.

Example # Create Node 10 for the IPv6 policy “aaa” with match mode being permit and
enter IPv6 policy routing view.
<Sysname> system-view
[Sysname] ipv6 policy-based-route aaa permit node 10
