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 [Sysname-pim6] ssm-policy 2000
