Configuring IPv6 PIM common features
For the configuration tasks in this section:
• In IPv6 PIM view, the configuration is effective on all interfaces. In interface view, the configuration
is effective on only the current interface.
• If the same function or parameter is configured in both IPv6 PIM view and interface view, the
configuration in interface view has preference over the configuration in PIM view, regardless of the
configuration sequence.

Configuration prerequisites
Before you configure IPv6 PIM common features, 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.
• Configure IPv6 PIM-DM (or IPv6 PIM-SM or IPv6 PIM-SSM).
• Determine the IPv6 ACL rule for filtering IPv6 multicast data.
• Determine the IPv6 ACL rule defining a legal source address range for hello messages.
• Determine the priority for DR election (global value/interface level value).
• Determine the IPv6 PIM neighbor timeout time (global value/interface value).
