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.
