PIM Mode-Independent Configuration Overview

You can configure several Protocol Independent Multicast (PIM) features on an interface regardless of its PIM mode (sparse, dense, or sparse-dense mode).

These features include:

• Configuring the PIM version. See Changing the PIM Version.
• Configuring priority to become the PIM DR. See Configuring Interface Priority to Become the PIM Designated Router.
• Configuring incoming and outgoing PIM join filtering. See Filtering Outgoing PIM Join Messages and Filtering Incoming PIM Join Messages.
• Configuring the PIM hello interval and hold time. See Modifying the PIM Hello Interval.
• Configuring the PIM neighbor policies. See Configuring Interface-Level PIM Neighbor Policies.
• Configuring a PIM RPF routing table. See Configuring a PIM RPF Routing Table.
• Configuring the BFD protocol for PIM. See Configuring the BFD Protocol for PIM.
• Configuring Nonstop Active Routing with PIM. See Configuring Nonstop Active Routing with PIM.

If you configure PIM on an aggregated (ae- or as-) interface, each of the interfaces in the aggregate is included in the multicast output interface list and carries the single stream of replicated packets in a load-sharing fashion. The multicast aggregate interface is “expanded” into its constituent interfaces in the next-hop database. For information about aggregate interfaces, see the Junos Network Interfaces Configuration Guide.
