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.
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.
Perform the following configuration on all routers in the IPv6 PIM-SM domain.
To configure the IPv6 SSM group range:
Step
1.
Enter system view.
2.
Enter IPv6 PIM view.
3.
Configure the IPv6 SSM group
range.
Configuring IPv6 PIM common features
For the functions or parameters that can be configured in both IPv6 PIM view and interface view
described in this section:
Configurations performed in IPv6 PIM view are effective on all interfaces, while configurations
•
performed in interface view are effective on the current interface only.
If the same function or parameter is configured in both IPv6 PIM view and interface view, the
•
configuration made in interface view has preference over the configuration made in PIM view,
regardless of the configuration sequence.

Configuration prerequisites
Before configuring IPv6 PIM common features, complete the following tasks:
Enable IPv6 forwarding and configure any IPv6 unicast routing protocol so that all devices in the
•
domain are interoperable at the network layer.
