Select the PIM mode here. Options to choose from are:  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 Multicast Route entry. A sparse mode interface will only be populated as Multicast Route 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 309
