Configuration prerequisites
Before you configure IPv6 PIM-SM, configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.
Enabling IPv6 PIM-SM
Enable IPv6 multicast routing before configuring IPv6 PIM.
With IPv6 PIM-SM enabled on interfaces, routers can establish IPv6 PIM neighbor relationship and
process IPv6 PIM messages from their IPv6 PIM neighbors. When you deploy an IPv6 PIM-SM domain,
H3C recommends that you enable IPv6 PIM-SM on all non-border interfaces.
IMPORTANT:
All the interfaces on the same router must operate in the same IPv6 PIM mode in the public network or the
same VPN instance.
To enable IPv6 PIM-SM:

Configuring an RP
An RP can provide services for multiple or all IPv6 multicast groups. However, only one RP can forward
IPv6 multicast traffic for an IPv6 multicast group at a moment.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled IPv6 PIM network, configuring static RPs is a tedious job. Generally, static RPs are backups
for dynamic RPs to enhance the robustness and operational manageability on an IPv6 multicast network.
