Adjusting BSR RP Parameters (IPv6)

Adjusting BSR RP Parameters (IPv6)

If a BootStrap router (BSR) Rendezvous Point (RP) is used, you can adjust parameters about Candidate-Rendezvous Points (C-RPs) and Candidate-BootStrap Routers (C-BSRs)

Usage Scenario

Initially, each C-BSR considers itself as a BSR and sends a Bootstrap message to the entire network. Each router receives the Bootstrap messages sent by all C-BSRs. By comparing the information carried by the Bootstrap messages, the routers elect a BSR.

All routers know the BSR address. The C-RPs send Advertisement messages to the BSR. An Advertisement message sent by a C-RP carries the address of the C-RP, the range of multicast groups that the C-RP serves, and the priority of the C-RP. The BSR collects C-RP information and summarizes information into an RP-Set, encapsulates the RP-Set in a Bootstrap message, and advertises the Bootstrap message to each router. Based on the RP-Set, each router performs the RP calculation by using the same rule and elects the RP for a specific group from multiple C-RPs to which this group corresponds.

The router can work normally by using default parameter values. The NE40E allows you to adjust BSR RP parameters as needed.


If there is no special requirement, default parameter values are recommended.

Pre-configuration Tasks

Before adjusting dynamic RP parameters, complete the following tasks:

  • Configure an IPv6 unicast routing protocol to ensure that IPv6 unicast routes are reachable.

  • Configure IPv6 PIM-SM and configure the system to use a BSR RP.

Configuration Procedures

Perform one or more of the following configurations as required.
