TABLE 8
Output of the show ip pim sparse command
This field...
Displays...
Global PIM Sparse mode settings
Hello interval
How frequently the device sends PIM Sparse hello messages to its PIM
Sparse neighbors. This field also shows the number of seconds between
hello messages. PIM Sparse devices use hello messages to discover
each another.
Neighbor timeout
How many seconds the device waits for a hello message from a neighbor
before determining that the neighbor is no longer present and removing
cached PIM Sparse forwarding entries for the neighbor.
Bootstrap Msg interval
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. A candidate RP group prefix 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.
Candidate-RP Advertisement interval
How frequently the candidate PR configured on the device sends
candidate RP advertisement messages to the BSR.
NOTE: This field contains a value only if an interface on the device is
configured as a candidate RP. Otherwise, the field is blank.
Join or Prune interval
How frequently the device sends PIM Sparse Join or Prune messages for
the multicast groups it is forwarding. This field also shows the number of
seconds between Join or Prune messages. The device sends Join or
Prune messages on behalf of multicast receivers who want to join or
leave a 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. You can change the Join or Prune interval. Refer to
PIM Join and Prune message interval”
.
SPT Threshold
The number of packets the device sends using the path through the RP
before switching to using the SPT path.
Inactivity Interval
SSM Enabled
If yes, source-specific multicast is configured globally on this device.
SSM Group Range
The SSM range of IP multicast addresses. By default this range will be
232/8 as assigned by the Internet Assigned Numbers Authority (IANA)
for use with SSM. Other values can be configured.
PIM Sparse interface information
NOTE: You also can display IP multicast interface information using the show ip pim interface command. However,
this command lists all IP multicast interfaces, including regular PIM (dense mode) and DVMRP interfaces.
The show ip pim sparse command lists only the PIM Sparse interfaces.
Interface
The type of interface and the interface number. The interface type can
be one of the following:
•
Ethernet
•
VE
The number is either a port number (and slot number if applicable) or
the virtual interface (VE) number.
