Output

The show ip pim bsr command displays the following information:


Output Field.	Description
BSR address	The IP address of the interface configured as the PIM Sparse BSR.
BSR priority	The priority assigned to the interface for use during the BSR election process. During BSR election, the priorities of the candidate BSRs are compared and the interface with the highest BSR priority becomes the BSR.
Hash mask length	The number of significant bits in the IP multicast group comparison mask. This mask determines the IP multicast group numbers for which the device can be a BSR. The default is 32 bits, which allows the device to be a BSR for any valid IP multicast group number. Note: This field appears only if this device is a candidate BSR.
Next bootstrap message in	Indicates how much time will pass before the BSR sends the next bootstrap message. The time is displayed in "hh:mm:ss" format. Note: This field appears only if this device is the BSR.
Next Candidate-RP-advertisement message in	Indicates how much time will pass before the BSR sends the next candidate PR advertisement message. The time is displayed in "hh:mm:ss" format. Note: This field appears only if this device is a candidate BSR.
RP	Indicates the IP address of the Rendezvous Point (RP). Note: This field appears only if this device is a candidate BSR.
group prefixes	Indicates the multicast groups for which the RP listed by the previous field is a candidate RP. Note: This field appears only if this device is a candidate BSR.
Candidate-RP-advertisement period	Indicates how frequently the BSR sends candidate RP advertisement messages. Note: This field appears only if this device is a candidate BSR.
