BigIron RX Series Configuration Guide 61153-1001810-01Anycast RP 23Displaying basic PIM Sparse configuration informationTo display PIM Sparse configuration information, enter the following command at any CLI level.Syntax: show ip pim sparseThis example shows the PIM Sparse configuration information on PIM Sparse router A in Figure 91.This display shows the following information.This field... Displays...Global PIM Sparse mode settingsHello interval How frequently the device sends PIM Sparse hello messages to its PIMSparse neighbors. This field show the number of seconds between hellomessages. PIM Sparse routers use hello messages to discover oneanother.Neighbor timeout How many seconds the device will wait for a hello message from aneighbor before determining that the neighbor is no longer present andremoving cached PIM Sparse forwarding entries for the neighbor.Bootstrap Msg interval How frequently the BSR configured on the device sends the RP set to theRPs within the PIM Sparse domain. The RP set is a list of candidate RPsand their group prefixes. A candidate RP’s group prefix indicates therange 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 iselected to be the BSR. Otherwise, the field is blank.Candidate-RP Advertisement interval How frequently the candidate PR configured on the device sendscandidate RP advertisement messages to the BSR.NOTE: This field contains a value only if an interface on the device isconfigured as a candidate RP. Otherwise, the field is blank.Join/Prune interval How frequently the device sends PIM Sparse Join/Prune messages forthe multicast groups it is forwarding. This field show the number ofseconds between Join/Prune messages.The device sends Join/Prune messages on behalf of multicast receiverswho want to join or leave a PIM Sparse group. When forwarding packetsfrom PIM Sparse sources, the device sends the packets only on theinterfaces on which it has received join requests in Join/Prunemessages for the source’s group.You can change the Join/Prune interval if needed.
