•
Dense Mode: PIM-DM assumes that when a source starts
sending, all downstream routers wants to receive the multicast
data stream. Initially multicast data stream are flooded to all
downstream routers and the interfaces that have group
members. If there are no downstream routers or group members,
the router will send prune message to indicate that the multicast
data stream is not desired.
•
Sparse Mode: When multicast traffic is received on a sparse
mode interface, the first hop router will encapsulate and send the
register message to RP. If the router is not the first hop router,
the traffic will be forwarded based on the mroute entry. A sparse
mode interface will only be populated as mroute member
interface if receive join message from the downstream router or if
group member on a sparse mode interface, PIM join process will
be triggered to create the shared tree or the source tree.
•
Sparse-Dense Mode: When interface is configured as PIM
Sparse-Dense mode, a multicast group received by the interface
can operate in either sparse mode or dense mode of operation.
When the interface receives multicast traffic, if there is a known
RP for the group, then this group will operate in sparse mode,
otherwise this multicast group will operate in dense mode.
