Usage Guidelines

Usage Scenario

This command is applicable to Rendezvous Point (RP) election in a PIM-SM domain. This command can be used to view BSR information on each Router in a PIM-SM domain.

If the current Router is configured with a Candidate-BootStrap Router (C-BSR), information about the elected BSR and locally configured C-BSR is displayed.
If the current Router is not configured with any C-BSR, only information about the elected BSR is displayed.

Precautions

This command has output only after C-BSRs have been configured in a PIM-SM domain.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display information about a BSR. If the Router is configured with a C-BSR, information about the elected BSR and the C-BSR is displayed.

**Table 1** Description of the **display pim ipv6 bsr-info** command output
Item	Description
Elected AdminScope BSR Count	Indicates the number of elected AdminScope BSRs.
Elected BSR Address	Indicates the IPv6 address of the elected BSR.
Hash mask length	Indicates the hash mask length for the RP calculation.
Next BSR message scheduled at	Indicates the period for waiting to receive the next BSR message. BSR messages are sent only when the timer maintained by the elected BSR times out.
C-RP Count	Indicates the number of C-RPs.
Candidate AdminScope BSR Count	Indicates the number of candidate AdminScope BSRs.
Candidate BSR Address	Indicates the IPv6 address of a C-BSR.
Wait to be BSR	Indicates whether the CBSR is valid.
VPN-Instance	Indicates the VPN instance to which BSR information belongs.
Priority	Indicates the BSR priority.
State	Indicates the BSR status. Accept Preferred: The router knows the identity of the current BSR, and is using the RP-Set provided by that BSR. Only Bootstrap messages from that BSR or from a C-BSR with higher weight than the current BSR will be accepted. Accept Any: The router does not know an active BSR, and will accept the first Bootstrap message it sees as giving the new BSR's identity and the RP-Set. This state exists only if a BSR administrative domain has been configured. Elected: The router is the elected BSR for the PIM-SM domain and it must perform all the BSR functions. Candidate: The router is a candidate to be the BSR for the PIM-SM domain, but currently another router is the preferred BSR. Pending: The router is a candidate to be the BSR for the PIM-SM domain. Currently, no other router is the preferred BSR, but this router is not yet the elected BSR. This is a temporary state that prevents rapid thrashing of the choice of BSR during BSR election. After the elected BSR fails, other C-BSRs enter the Pending state.
Uptime	Indicates the running time of the BSR.
