By default, the IPv6 SSM group range is FF3x::/32, where x represents any legal
scope.
This command allows you to define an address range of permitted or denied IPv6
multicast sources or IPv6 multicast groups. If the match succeeds, the running
multicast mode will be IPv6 PIM-SSM; otherwise the multicast mode will be IPv6
PIM-SM.
Example # Configure FF3E:0:8192::/96 as the IPv6 SSM group range.
<Sysname> system-view
[Sysname] acl ipv6 number 2000
[Sysname-acl6-basic-2000] rule permit source ff3e:0:8192:: 96
[Sysname-acl6-basic-2000] quit
[Sysname] pim ipv6
