Sparse-Dense Mode PIM
“Sparse-dense mode” automatically works in sparse mode for groups with a RP, and in dense mode for groups without a RP. This is the suggested mode to initially implement multicast support
- Start without RPs (runs dense mode)
- Add RPs where sparse-mode characteristics are needed (automatically shifts to sparse mode)
- Configure Auto-RP for load balancing and efficient communication between group members and RPs
