How frequently the device sends IPv6 PIM Sparse Join or Prune
messages for the multicast groups it is forwarding. This field shows the
number of seconds between Join or Prune messages.
The device sends Join or Prune messages on behalf of multicast
receivers that want to join or leave an PIM Sparse group. When
forwarding packets from PIM Sparse sources, the device sends the
packets only on the interfaces on which it has received join requests in
Join or Prune messages for the source group.
Number of seconds a forwarding entry can remain unused before the
router deletes it. Default is 180 sec.
Indicates whether hardware drop is enabled or disabled.
To prevent unwanted multicast traffic from being sent to the CPU, PIM
Routing and Passive Multicast Route Insertion (PMRI) can be used
together to ensure that multicast streams are only forwarded out ports
with interested receivers and unwanted traffic is dropped in the
hardware on Layer 3 Switches.
Number of seconds a PIM device waits before stopping traffic to
neighbor devices that do not want the traffic. Range is from zero to three
seconds. Default is three seconds.
How frequently the BSR configured on the device sends the RP set to the
RPs within the PIM Sparse domain. The RP set is a list of candidate RPs
and their group prefixes. The group prefix of a candidate RP indicates
the range of PIM Sparse group numbers for which it can be an RP.
NOTE: This field contains a value only if an interface on the device is
elected to be the BSR. Otherwise, the field is blank.
Number of seconds the candidate RP configured on the Layer 3 switch
sends candidate RP advertisement messages to the BSR. Default is 60
seconds.
This is the mean interval between receiving a Register-Stop and allowing
registers to be sent again. A lower value means more frequent register
bursts at RP, while a higher value means longer join latency for new
receivers. Default: 60 seconds.
Number of seconds the PIM router waits for a register-stop from an RP
before it generates another NULL register to the PIM RP. Default is 10
seconds.
Register stop message. Default is 10 seconds.
Number of seconds that it takes the designated router to send a
Register-encapsulated date to the RP after receiving a Register-Stop
message. Default is 60 seconds.
If yes, source-specific multicast is configured globally on this router.
Number of packets the device sends using the path through the RP
before switching to the SPT path. Default is 1 packet.
Source-specific multicast group range.
