Configuring IPv6 PIM-DM
IPv6 PIM-DM configuration task list
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 enable IPv6 PIM-DM, follow these guidelines:
• When you deploy an IPv6 PIM-DM domain, enable IPv6 PIM-DM on all non-border interfaces of
routers.
• All the interfaces of the same device must operate in the same IPv6 PIM mode.
• IPv6 PIM-DM cannot be used for IPv6 multicast groups in the IPv6 SSM group range.
To enable IPv6 PIM-DM:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enable IPv6 multicast routing. multicast ipv6 routing-enable Disable by default.
