The fields that can be configured are described below:
Parameter
Hello Interval (1-18724)
Enter 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.
The drop-down menu 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.

Description
This field will set the interval time between the sending of Hello Packets from this IP
interface to neighboring routers one hop away. These Hello packets are used to
discover other PIM enabled routers and state their priority as the Designated Router
(DR) on the PIM enabled network. The user may state an interval time between 1
and 18724 seconds with a default interval time of 30 seconds.
