Usage guidelines
This command defines a multicast group range that is used by PIM-SSM. For multicast packets that are permitted by the ACL, the PIM-SSM mode is used. For multicast packets that are not permitted by the ACL, the PIM-SM mode is used.
When you configure a rule in the IPv4 basic ACL, follow these restrictions and guidelines:
For the rule to take effect, do not specify the vpn-instance vpn-instance option.
The source source-address source-wildcard option specifies a multicast group range.
Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.
If you execute this command multiple times, the most recent configuration takes effect.
