Parameters
source-address: Specifies a multicast source by its IP address.
ipv4-acl-number: Specifies a basic ACL number in the range of 2000 to 2999. Multicast groups in IGMP reports permitted by the ACL are associated with the IPv6 multicast source. If the ACL does not exist or does not have valid rules, no multicast groups are associated with the IPv6 multicast source.
all: Specifies all IGMP SSM mappings.
Usage guidelines
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 address.
Among the other optional parameters, only the fragment keyword and the time-range time-range-name option take effect.
Examples
# Configure an IGMP SSM mapping with multicast source 125.1.1.1 and multicast group range 232.1.1.0/24 on the public network.
<Sysname> system-view [Sysname] acl basic 2001 [Sysname-acl-ipv4-basic-2001] rule permit source 232.1.1.1 0.0.0.255 [Sysname-acl-ipv4-basic-2001] quit [Sysname] igmp [Sysname-igmp] ssm-mapping 125.1.1.1 2001
