Configuring a BSR Administrative Domain

A PIM-SM network can be divided into multiple bootstrap router (BSR) administrative domains and a global domain. This effectively reduces the load of a single BSR, and provides a special service for specific multicast groups.

Enabling a BSR Administrative Domain: This section describes how to enable BSR administrative domains on all devices in a PIM-SM network.

Configuring the Boundary of a BSR Administrative Domain: After an interface is configured as a BootStrap router (BSR) administrative domain boundary, all the multicast packets for the groups in this BSR administrative domain cannot pass this interface.

Adjusting C-BSR Parameters: You can adjust the Candidate-BSR (C-BSR) parameters of the BootStrap router (BSR) administrative domain and the global domain as required.
