NOTE:
Generally, a BSR performs BSM semantic fragmentation according to the MTU of its BSR interface. For
BSMs originated due to learning of a new IPv6 PIM neighbor, semantic fragmentation is performed
according to the MTU of the interface that sends the BSMs.
Configuring IPv6 PIM-SSM
IPv6 PIM-SSM requires MLDv2 support. Enable MLDv2 on IPv6 PIM routers that connect to multicast
receivers.

Configuration prerequisites
Before you configure IPv6 PIM-SSM, configure an IPv6 unicast IPv6 routing protocol so that all devices in
the domain are interoperable at the network layer.
Enabling IPv6 PIM-SM
The implementation of the IPv6 SSM model is based on 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 non-border interfaces of the
routers.
IMPORTANT:
All the interfaces on a device must be enabled with the same IPv6 PIM mode.
To enable IPv6 PIM-SM:
Step
1.
Enter system view.
2.
Enable IP multicast routing,
and enter MRIB view.
3.
Return to system view.
4.
Enter interface view.
5.
Enable IPv6 PIM-SM.
