interface list if RP is not found. In other words, the PIM Sparse-Dense mode is treated in either the sparse mode or dense mode of
the operation; it depends on which mode the multicast group operates. When an interface receives multicast traffic, if there is a
known RP for the group, then the current operation mode on the interface is sparse mode, otherwise the current operation mode on
the interface will be dense mode.

PIM Global Settings

Description
This field is used by the last hop router to decide whether to receive multicast data from the
shared tree or switch over to the shortest path tree. When the switchover mode is set to
never, the last hope router will always receive multicast data from the shared tree. When the
mode is set to immediately, the last hop router will always receive data from the shortest path
tree.
This command is used to set a time to send a probe message from the DR to the RP before
the Register Suppression time expires. If a Register Stop message is received by the DR, the
Register Suppression Time will be restarted. If no Register Stop message is received within
the probe time, Register Packets will be resent to the RP. The user may configure a time
between 1 and 127 seconds with a default setting of 5 seconds.
This field is to be configured for the first hop router from the source. After this router sends
out a Register message to the RP, and the RP replies with a Register stop message, it will
wait for the time configured here to send out another register message to the RP. The user
may set a time between 3 and 255 with a default setting of 60 seconds.
