Configuring IPv6 PIM-DM
IPv6 PIM-DM configuration task list
Complete these tasks to configure IPv6 PIM-DM:
Task Remarks
Enabling IPv6 PIM-DM Required
Enabling state-refresh capability Optional
Configuring state refresh parameters Optional
Configuring IPv6 PIM-DM graft retry period Optional
Configuring IPv6 PIM common features Optional
Configuration prerequisites
Before you configure IPv6 PIM-DM, complete the following tasks:
• Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
domain are interoperable at the network layer.
• Determine the interval between state refresh messages.
• Determine the minimum time to wait before receiving a new refresh message.
• Determine the hop limit value of state-refresh messages.
• Determine the graft retry period.
Enabling IPv6 PIM-DM
With IPv6 PIM-DM enabled, a router sends hello messages periodically to discover IPv6 PIM neighbors
and processes messages from the IPv6 PIM neighbors. When you deploy an IPv6 PIM-DM domain,
enable IPv6 PIM-DM on all non-border interfaces of routers.
Follow these steps to enable IPv6 PIM-DM:

CAUTION:
•
All the interfaces of the same device must work in the same IPv6 PIM mode.
• IPv6 PIM-DM cannot be used for IPv6 multicast groups in the IPv6 SSM group range.
