Configuring the IPv6 SSM group range
When an IPv6 PIM-SM enabled interface receives an IPv6 multicast packet, it checks whether the IPv6
multicast group address of the packet is in the IPv6 SSM group range. If the IPv6 multicast group address
is in this range, the IPv6 PIM mode for this packet is IPv6 PIM-SSM. If the IPv6 multicast group address is
not in this range, the IPv6 PIM mode is IPv6 PIM-SM.
Configuration guidelines
Perform the following configuration on all routers in the IPv6 PIM-SSM domain.
•
Make sure the same IPv6 SSM group range is configured on all routers in the entire domain.
•
Otherwise, IPv6 multicast information 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.
Configuration procedure
To configure an IPv6 SSM group range:
Step
1.
Enter system view.
2.
Enter IPv6 PIM view.
3.

range.
