PIM Sparse

Syntax: show ip pim sparse
This example shows the PIM Sparse configuration information on PIM Sparse router A in Figure 87.
This display shows the following information.
TABLE 75 Output of show ip pim sparse
This field... Displays...
Global PIM Sparse mode settings
Hello interval How frequently the Layer 3 Switch sends PIM Sparse hello messages to its PIM Sparse
neighbors. This field show the number of seconds between hello messages. PIM Sparse
routers use hello messages to discover one another.
Neighbor timeout How many seconds the Layer 3 Switch will wait 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 Layer 3 Switch 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 Layer 3 Switch is elected to
be the BSR. Otherwise, the field is blank.
Candidate-RP
Advertisement
interval
How frequently the candidate PR configured on the Layer 3 Switch sends candidate RP
advertisement messages to the BSR.
NOTE: This field contains a value only if an interface on the Layer 3 Switch is configured
as a candidate RP. Otherwise, the field is blank.
Join/Prune interval How frequently the Layer 3 Switch sends PIM Sparse Join/Prune messages for the
multicast groups it is forwarding. This field show the number of seconds between
Join/Prune messages.
The Layer 3 Switch sends Join/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 Layer 3 Switch sends the packets only on the interfaces on which it has
received join requests in Join/Prune messages for the source group.
You can change the Join/Prune interval if needed. Refer to “Changing the PIM join and
prune message interval” on page 484.
SPT Threshold The number of packets the Layer 3 Switch sends using the path through the RP before
switching to using the SPT path.
