Description
Click the radio buttons to enable or disable PIM global state.
Enter a time to send a NULL register 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.
