# Displaying the PIM-SM RP set

Use the following procedure to display the RP set for troubleshooting purposes. The BSR constructs the RP set from C-RP advertisements and then distributes it to all PIM routers in the PIM domain for the BSR.

## Procedure steps

1. From the navigation tree, double-click IP Routing.

2. In the IP Routing tree, double-click PIM.

3. In the work area, click the RP Set tab to view RP Set information.

## Variable definitions

The following table describes the fields of the RP Set tab.

HoldTime(sec) | Indicates the time specified in a C-RP advertisement that the BSR uses to time out the RP. After the BSR receives an advertisement for the RP, it restarts the timer. If no advertisement arrives before the timer expires, the BSR removes that RP from the RP set.
ExpiryTime | Specifies the time remaining before this C-RP times out.
