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,
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.
To enable IPv6 PIM-DM:
Step
1. Enter system view.
2. Enable IPv6 multicast routing.
3. Enter interface view.
4. 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,
which is forwarded hop-by-hop along the initial flooding path of the IPv6 PIM-DM domain, to refresh the
prune timer state of all the routers on the path. A shared-media subnet can have the state refresh feature
only if the state refresh feature is enabled on all IPv6 PIM routers on the subnet.
To enable the state refresh feature on all routers in IPv6 PIM-DM domain:
Configuring state refresh parameters
Configuring IPv6 PIM-DM graft retry timer
Configuring common IPv6 PIM features
