pim bsr-boundary

Function

The pim bsr-boundary command configures the BSR boundary of a PIM-SM domain on an interface.

The undo pim bsr-boundary command restores the default configuration.

By default, the BSR boundary of a PIM-SM domain is not set.

Usage Guidelines

Usage Scenario

As the management core of the PIM-SM network, the BSR is responsible for sending collected RP-set information to PIM neighbors through Bootstrap messages.

You can divide a large PIM-SM network into multiple PIM-SM domains by configuring the bsr boundary on an interface. Each BSR then serves the local PIM-SM domain.

Prerequisites

IP multicast routing has been enabled using the multicast routing-enable command.

Configuration Impact

The Bootstrap messages cannot traverse the BSR boundary but other multicast packets can.

Example

# Configure the BSR boundary of a PIM-SM domain on VLANIF100.

<HUAWEI> system-view
[HUAWEI] multicast routing-enable
[HUAWEI] interface vlanif 100
[HUAWEI-Vlanif100] pim bsr-boundary

# Configure the BSR boundary of a PIM-SM domain on GE0/0/1.

<HUAWEI> system-view
[HUAWEI] multicast routing-enable
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] undo portswitch
[HUAWEI-GigabitEthernet0/0/1] pim bsr-boundary
