PIM operational modes

PIM can operate in a number of modes:

  • Dense mode (PIM-DM)
  • Sparse mode (PIM-SM)
  • Sparse-dense mode (PIM-SDM)
  • Bidirectional PIM (BIDIR-PIM)
  • Nonbroadcast multiaccess (NBMA) mode

Each mode is suited to a particular environment. The vRouter supports PIM-DM, PIM-SM, and sparse-dense mode.

PIM also supports Any Source Multicast (ASM) and Source-Specific Multicast (SSM). ASM and SSM are described in Ciena Vyatta Network OS Multicast Routing Configuration Guide.
