Enabling IPv6 PIM-SM
The implementation of the SSM model is based on some subsets of IPv6 PIM-SM. Therefore, you must
enable IPv6 PIM-SM before configuring IPv6 PIM-SSM.
When you deploy an IPv6 PIM-SSM domain, enable IPv6 PIM-SM on all non-border interfaces of routers.
IMPORTANT:
A
ll the interfaces on a device must be enabled with the same IPv6 PIM mode.
To enable IPv6 PIM-SSM:

1. Enter system view.

Configuring the IPv6 SSM group range
Whether the IPv6 PIM-SSM model or the IPv6 PIM-SM model delivers the information from an IPv6
multicast source depends on whether the group address in the (S, G) packet that the receivers request is
in the IPv6 SSM group range. All IPv6 PIM-SM-enabled interfaces assume the IPv6 PIM-SSM model for
IPv6 multicast groups within this address range.
When you configure the IPv6 SSM group range, follow these guidelines:
• Make sure 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-SSM domain.
