H3C S7500E Series Ethernet Switches Chapter 4 PIM Configuration Commands
4-49
Note that:
z If you specify a basic ACL, the device filters all the received multicast packets
based on the source address, and discards packets that fail the source address
match.
z If you specify an advanced ACL, the device filters all the received multicast
packets based on the source and group addresses, and discards packets that fail
the match.
z If this command is executed repeatedly, the last configuration will take effect.
Examples
# Configure the router to accept multicast packets originated from 10.10.1.2 and
discard multicast packets originated from 10.10.1.1.

Parameters
infinity: Disables RPT-to-SPT switchover.
group-policy acl-number: Uses this threshold for multicast groups matching the
specified multicast policy. In this option, acl-number refers to a basic ACL number, in
the range of 2000 to 2999. If you do not include this option in your command, the
threshold will apply on all multicast groups.
order order-value: Specifies the order of the ACL in the group-policy list, where
order-value has an effective range of 1 to (the largest order value in the existing
group-policy list + 1), but the value range should not include the original order value of
the ACL in the group-policy list. If you have assigned an order-value to a certain ACL,
do not specify the same order-value for another ACL; otherwise the system will give
