Parameter
policy-name: Specifies the name of a route-policy, which uniquely identifies one
route-policy.
permit: Specifies the match mode of the route-policy node defined as permit. When a
route entry meets the if-match clause of the node, the entry is permitted to pass the
filter of the node and the apply clause of the node will be performed. If a route entry
does not meet the if-match clause of the node, the next node of the route-policy will be
tested. For multicast policy routing configuration, all the if-match clauses except the
if-match acl clause are invalid.
deny: Specifies the match mode of the route-policy node defined as deny. When a
route entry meets the if-match clause of the node, the entry is denied to pass the filter
of the node and the next node will not be tested. For multicast policy routing
configuration, all the if-match clauses except the if-match acl clause are invalid.
sequence-number: Identifies a node in the route-policy. When the route-policy is used
for routing information filtering, the node with a smaller sequence-number is tested first.
This parameter ranges from 0 to 65535.
Description
Use the route-policy command to configure a route-policy node and enter the
route-policy view.
Use the undo route-policy command to remove a route-policy or a node.
By default, no route-policy is defined.
The policy of IP multicast policy routing is implemented by configuring route-policies.
Multiple route-policies can be configured on the router. Each route-policy may contain
multiple route-nodes. Different route-nodes in a route-policy are identified by different
integer sequence-numbers. In each route-node, set the conditions that packets should
match (that is, the match rule) with the if-match command and configure the
forwarding actions to be executed to packets that meet the match conditions with the
apply command.
The logical relation that filter the if-match clauses is “and”. This means that any if-match
clause passing the filter will cause others to be ignored.
Only the if-match acl clause is effective for multicast policy routing. The logical relation
between route-policy nodes is “or”. That is, one packet forwarded in one policy node
