Protocol Independent Multicast—Sparse Mode

Protocol Independent Multicast-Sparse Mode (PIM-SM) is used to efficiently

route multicast traffic to multicast groups that may span wide area networks,

and where bandwidth is a constraint. PIM-SM uses shared trees by default

and implements source-based trees for efficiency. This data threshold rate is

used to toggle between trees.

Protocol Independent Multicast—Source Specific Multicast

Protocol Independent Multicast—Source Specific Multicast (PIM-SSM) is a

subset of PIM-SM and is used for one-to-many multicast routing

applications, such as audio or video broadcasts. PIM-SSM does not use shared

PIM-DM and PIM-SM support IPv6 routes.

MLD is used by IPv6 systems (listeners and routers) to report their IP

multicast addresses memberships to any neighboring multicast routers. The

implementation of MLD v2 is backward compatible with MLD v1.

MLD protocol enables the IPv6 router to discover the presence of multicast

listeners, the nodes that want to receive the multicast data packets, on its

directly attached interfaces. The protocol specifically discovers which

multicast addresses are of interest to its neighboring nodes and provides this

information to the multicast routing protocol that make the decision on the

flow of the multicast data packets.
