Overview of PIM-DM (IPv4)

The key mechanisms of PIM-DM are neighbor discovery, flooding, prune, graft, assert, and state refresh.

Overview of PIM-DM: In the network where multicast group members are densely distributed and each network segment may have multicast group members, Protocol Independent Multicast-Dense Mode (PIM-DM) builds a unidirectional and loop-free shortest path tree (SPT) from the multicast source to the group member through periodical flooding and pruning.

PIM-DM Features Supported: The system can work normally with default PIM-DM parameters. You are also allowed to adjust parameters related to neighbor discovery, prune, state refresh, graft, and assert according to specific scenarios. In addition, you can configure various filtering policies and the PIM silent function to enhance the PIM-DM security.
