PIM modes

Based on the implementation mechanism, PIM includes the following modes:

• Protocol Independent Multicast–Dense Mode (PIM-DM).

• Protocol Independent Multicast–Sparse Mode (PIM-SM).

• Bidirectional Protocol Independent Multicast (BIDIR-PIM).

• Protocol Independent Multicast Source-Specific Multicast (PIM-SSM).

In this document, a PIM domain refers to a network that contains PIM devices.
