Configuring a BSR Boundary (IPv6)

Configuring a BSR Boundary (IPv6)

Before configuring IPv6 PIM-SM inter-domain multicast, configure BootStrap router (BSR) boundaries to divide a multicast network into different PIM-SM domains. Each BSR serves only the local PIM-SM domain, and routers outside the BSR boundary of a PIM-SM domain do not take part in BSR messages forwarding in the PIM-SM domain.

Usage Scenario

After a BSR boundary is configured on the interface of an edge router in an IPv6 PIM-SM domain, Bootstrap messages cannot pass through this interface. The interfaces configured with BSR boundaries divide a network into different PIM-SM domains.

BSR boundaries can also be used to isolate PIM-SM domains from the Internet.

Pre-configuration Tasks

Before configuring a BSR boundary, complete the following tasks:

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

  • Enable IPv6 multicast routing on all routers and enable IPv6 PIM-SM on each interface on the routers.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run pim ipv6 bsr-boundary

    A BSR boundary is configured. Bootstrap messages cannot pass through the BSR boundary.

  4. Run commit

    The configuration is committed.

Checking the Configurations

Run the display pim ipv6 bsr-info command to check information about the BSR in an IPv6 PIM-SM domain.

Follow-up Procedure

Configure a BSR RP in each IPv6 PIM-SM domain.
