Configuration prerequisites

Before you configure IPv6 PIM-DM, configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.

Enabling IPv6 PIM-DM

Enable IPv6 multicast routing before configuring IPv6 PIM.
With IPv6 PIM-DM 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-DM domain,
HP recommends that you enable IPv6 PIM-DM on all non-border interfaces of routers.
IMPORTANT:
All the interfaces on a device must operate in the same IPv6 PIM mode in the public network or the same
VPN instance.
To enable IPv6 PIM-DM:
Step
1. Enter system view.
2. Enable IPv6 multicast routing
and enter IPv6 MRIB view.
3. Return to system view.
4. Enter interface view.
5. Enable IPv6 PIM-DM.

Enabling the state refresh feature

Pruned interfaces resume multicast forwarding when the pruned state times out. To prevent this, the router
directly connected with the IPv6 multicast source periodically sends an (S, G) state refresh message. The
state refresh message is forwarded hop-by-hop along the initial flooding path of the IPv6 PIM-DM
