PIM on Aggregated Interfaces

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

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.

Platform-Specific PIM Mode Behavior

ACX Series

  • Support only sparse mode. Dense mode on ACX series is supported only for control multicast groups for auto-discovery of rendezvous point (auto-RP).
