c-bsr scope

Function

The c-bsr scope command specifies the scope ID of the BSR administrative domain served by a C-BSR.

The undo c-bsr scope command restores the default configuration.

By default, no scope ID is specified for a C-BSR. That is, the C-BSR does not belong to any BSR administrative domain.

Format

c-bsr scope scope-id [ hash-length hash-length | priority priority ] ^*

undo c-bsr scope scope-id

Parameters

Parameter	Description	Value
scope-id	Specifies the scope ID of the administrative domain served by a C-BSR.	The value is an integer that ranges from 3 to 15.
hash-length hash-length	Specifies the hash mask length of a C-BSR in a BSR administrative domain.	The value is an integer that ranges from 0 to 128. The default value is 126.
priority priority	Specifies the priority of a C-BSR in a BSR administrative domain.	The value is an integer that ranges from 0 to 255. The default value is 0. The greater the value, the higher the priority.

Usage Guidelines

Usage Scenario

Each BSR administrative domain is assigned a scope ID. To configure a C-BSR to serve a BSR administrative domain, use the c-bsr scope command to specify the scope ID of the BSR administrative domain. Packets forwarded by the C-BSR cannot travel across the boundary of the BSR administrative domain.

Prerequisites

IPv6 multicast routing has been enabled using the multicast ipv6 routing-enable command in the system view.

A BSR administrative domain has been configured using the c-bsr admin-scope (IPv6) command in the PIM-IPv6 view.

Precautions

The multicast group that does not belong to any BSR administrative domain belongs to a global domain.

Example

# In the PIM-IPv6 view, configure the switch as a C-BSR in the BSR administrative domain to serve groups of Scope 5, and set the priority of the C-BSR to 10.
