Configuration prerequisites

Before you configure IPv6 PIM-DM, configure an IPv6 unicast routing protocol so that all devices in
the domain can interoperate 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. As a best practice, enable IPv6 PIM-DM
on all non-border interfaces of routers when you deploy an IPv6 PIM-DM domain.
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
In an IPv6 PIM-DM domain, this feature enables the IPv6 PIM router that is directly connected to the
source to periodically send state refresh messages. It also enables other PIM routers to refresh
pruned state timers after receiving the state refresh messages. It prevents the pruned interfaces
from resuming multicast forwarding. You must enable this feature on all IPv6 PIM routers on a
subnet.
To enable the state refresh feature:
