Adjusting BSR RP Parameters

Adjusting BSR RP Parameters

If a BSR RP is used, you can adjust parameters about C-RPs and C-BSRs and configure a BSR administrative domain.

Usage Scenario

Initially, each C-BSR considers itself as a BSR and sends Bootstrap messages carrying the C-BSR addresses and C-BSR priorities on the entire network. Each router receives the Bootstrap messages sent by all C-BSRs. The router then compares these messages and elects a BSR. All routers use the same election rule and therefore the elected BSRs are the same.

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

The router can work normally with default control parameters. You are allowed to adjust BSR RP parameters based on the specific networking environment.

NOTE:

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

Pre-configuration Tasks

Before adjusting BSR RP parameters, complete the following tasks:

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

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

Configuration Procedures

Perform one or more of the following configurations as required.
