like the traditional PIM-SM6, but leave out the shared tree and RP management in PIM-S6M.
In SSM6, SPT tree will be constructed with (S,G). G for the multicast group address and S for
the source address of the multicast which sends datagram to G. (S,G) in a pair is named as a
channel of SSM6. SSM6 serves best for the application of multicast service which is from one
station to many ones, for example, the network sports video channel, and the news channel.
By default, the multicast group address of SSM6 is limited to ff3x::/32. However this address
range can be extended according to actual situations.
PIM-SSM6 can be supported in the PIM-DM6 environment.
29.4.2 PIM-SSM6 Configuration Task List
Command

ipv6 pim ssm {default|range <access-list-number>}
no ipv6 pim ssm
To configure address range for
pim-ssm multicast group. The
no prefix will disable this
command.
29.4.3 PIM-SSM6 Configuration Example
As it is shown in the below figure, ethernet interfaces of switchA, switchB, switchC, and
switchD are separated into different vlan. And PIM-SM6 or PIM-DM6 is enabled on all the vlan
interfaces. Take configuration of PIM-SM6 for example.
