PIM-SM
Protocol-independent multicast sparse mode (PIM-SM) is used to efficiently route multicast 
traffic to multicast groups that can span wide area networks where bandwidth is a constraint.

PIM-SM uses shared trees by default and implements source-based trees for efficiency; it 
assumes that no hosts want the multicast traffic unless they specifically ask for it. It creates a 
shared distribution tree centered on a defined rendezvous point (RP). Traffic from this source
