Parameters
ipv6-source-address: Specifies an IPv6 multicast source by its IPv6 address.
ipv6-acl-number: Specifies an IPv6 basic ACL number in the range of 2000 to 2999. IPv6 multicast groups in MLD 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 IPv6 multicast groups are associated with the IPv6 multicast source.
all: Specifies all MLD SSM mappings.
Usage guidelines
When you configure a rule in the IPv6 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-prefix option specifies an IPv6 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 MLD SSM mapping with IPv6 multicast source 1::1 and IPv6 multicast group range FF3E::/64 on the public network.
<Sysname> system-view [Sysname] acl ipv6 basic 2001 [Sysname-acl-ipv6-basic-2001] rule permit source ff3e:: 64 [Sysname-acl-ipv6-basic-2001] quit [Sysname] mld [Sysname-mld] ssm-mapping 1::1 2001
