Use this command to configure Source Specific Multicast (SSM) mode for the default or a specified multicast group range.
| default | Specifies that PIM SSM is enabled with the default address-group. The default address groups are enabled for ff34:0000::/16, ff35:0000::/16, ff38:0000::/16 and ff3e:0000::/16. |
| group-address/length | Specifies that PIM SSM is enabled with the specified IPv6 address range. |
None.
Configuration command.
The “no” form of this command removes PIM SSM configuration. PIM SSM is disabled by default.
When PIM SSM is enabled, the following IPv6 address ranges are enabled by default: ff34:0000::/16, ff35:0000::/16, ff38:0000::/16 and ff3e:0000::/16. The PIM SSM IPv6 address range is limited to is ff3x::/32 where (x = 4,5,8, or E).
This example enables PIM SSM for the default group ranges and for a user defined group range of ff3e:2000::/64:
System(su)->configure System(su-config)->ip pim ssm default System(su-config)->ip pim ssm ff3e:2000::/64
