multicast extranet select-rpf

Function

The multicast extranet select-rpf command configures a multicast routing policy for a VPN instance, specifying that the upstream interface of the RPF route selected by the PIM entry corresponding to a multicast group address belongs to another VPN or public network instance.

The undo multicast extranet select-rpf command deletes the multicast routing policy of a VPN instance.

By default, no multicast routing policies are configured for VPN instances.

Format

multicast extranet select-rpf public group group-address { group-mask | group-mask-length }

multicast extranet select-rpf vpn-instance vpn-instance-name group group-address { group-mask | group-mask-length }

undo multicast extranet select-rpf all

undo multicast extranet select-rpf public group group-address { group-mask | group-mask-length }

undo multicast extranet select-rpf vpn-instance vpn-instance-name group group-address { group-mask | group-mask-length }

Parameters

Parameter	Description	Value
group-mask	Specifies the mask of a multicast group address.	The value ranges from 240.0.0.0 to 255.255.255.255, in dotted decimal notation.
group-mask-length	Specifies the mask length of a multicast group address.	The value is an integer ranging from 4 to 32.
vpn-instance vpn-instance-name	Specifies the name of a VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string.
group group-address	Specifies a multicast group address range for PIM entries to which a multicast routing policy applies.	The value is a string case-sensitive characters, spaces not supported.
all	Indicates all multicast routing policies.	-

Usage Guidelines

Usage Scenario

MVPN extranet enables a service provider on a VPN to provide multicast services for users on other VPNs. To configure MVPN extranet in remote cross scenarios where a source VPN instance is configured on a receiver PE, run the multicast extranet select-rpf command to configure a multicast routing policy, specifying that the upstream interface of the RPF route selected by the PIM entry corresponding to a multicast group address belongs to another VPN or public network instance.

Prerequisites

The multicast routing-enable command has been configured in the VPN.

Precautions

vpn-instance-name specified in the multicast extranet select-rpf command cannot be the current VPN instance. If the upstream interface of an RPF route belongs to a public network instance, public must be selected.
The group address range specified in the newly configured multicast routing policy cannot overlap the existing group address range.

Example

# Configure a multicast routing policy for a VPN instance named vpn1, specifying that the upstream interface of the RPF route to the group address 225.1.1.0/24 belongs to a VPN instance named vpn2.
