Parameter
Description
Using the if-match acl command, you can set conditions that multicast packets
should meet in each policy node. Using the undo if-match acl command, you can
remove the match conditions set.
By default, no if-match clause is defined.
If a packet meets the if-match conditions specified in a policy node, actions
specified by the node will be performed. If a packet does not meet the if-match
conditions specified in a policy node, the next node will be detected. If a packet
does not meet the conditions of all policy nodes, the packet will return to the
normal forwarding flow. The configuration and use of this command are the same
as those of the same command in the unicast policy routing.

Parameter
policy-name: Specifies the name of a route-policy, which uniquely identifies one
route-policy.
Description
Using the ip multicast-policy route-policy command, you can enable a multicast
policy routing on an interface. Using the undo ip multicast-policy route-policy
command, you can remove a multicast policy route applied on the interface.
By default, no multicast route policy is enabled.
Using this command can enable multicast policy routing defined by the
route-policy named policy-name on an interface.
When multicast policy routing is configured on an interface of a router, all
multicast packets entering the router on the interface will be filtered.
The filter method is that all policy nodes of the route-policy specified by the policy
routing are tried in the order of the ascending sequence of the numbers. If a
packet meets the if-match conditions specified in a policy node, actions specified
by the node will be performed. If a packet does not meet the if-match conditions
specified in a policy node, the next node will be detected. If a packet does not
meet the conditions of any policy nodes, the packet will return to the normal
forwarding flow.
For the related command, see route-policy.
acl-number: Standard or extended ACL number ranging from 1 to 199.
ip-prefix-name: Specifies the name of an address prefix list used for filtering.
