Configuring IPv6 PIM-DM
IPv6 PIM-DM configuration task list
Complete these tasks to configure IPv6 PIM-DM:
Task
Enabling IPv6 PIM-DM
Enabling state-refresh capability
Configuring state refresh parameters
Configuring IPv6 PIM-DM graft retry period
Configuring IPv6 PIM common features
Configuration prerequisites
Before you configure IPv6 PIM-DM, complete the following tasks:
Enable IPv6 forwarding and configure any 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:
To do...
Enter system view
Enable IPv6 multicast routing
Enter interface view
Enable IPv6 PIM-DM
CAUTION:
All 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.
