All the interfaces of the same device must work in the same IPv6 PIM mode.
For details about the multicast ipv6 routing-table command, see IPv6 Multicast Routing and
Forwarding Configuration Commands in the IP Multicast Command Reference.
Configuring the IPv6 SSM Group Range
As for whether the information from an IPv6 multicast source is delivered to the receivers based
on the IPv6 PIM-SSM model or the IPv6 PIM-SM model, this depends on whether the group
address in the (S, G) channel subscribed by the receivers falls in the IPv6 SSM group range. All
IPv6 PIM-SM-enabled interfaces assume that IPv6 multicast groups within this address range
are using the IPv6 SSM model.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
Follow these steps to configure the IPv6 SSM group range:

refers to any legal group scope.
z Make sure that the same IPv6 SSM group range is configured on all routers in the entire
domain. Otherwise, IPv6 multicast data cannot be delivered through the IPv6 SSM model.
z When a member of an IPv6 multicast group in the IPv6 SSM group range sends an MLDv1
report message, the device does not trigger a (*, G) join.
