Configuring MVPN extranet

MVPN extranet overview

MVPN extranet implements inter-VPN multicast traffic transmission. In MVPN extranet, the multicast source and receivers are in different VPNs. In actual application, the MVPN extranet solution ensures that the service provider in a VPN provides multicast services for users in other VPNs.

The following terms are used in the MVPN extranet solution:

·     Source VPN instance—VPN instance to which the multicast source belongs.

·     Receiver VPN instance—VPN instance to which the multicast receiver belongs.

·     Source PE—PE directly connected to the multicast source.

·     Receiver PE—PE directly connected to multicast receivers.

As shown in Figure 1, multicast source Source 1 is in Site 1 of VPN A. Receiver 1 and Receiver 2 are located in Site 2 of VPN A and Site 1 of VPN B, respectively. MVPN enables Receiver 1 to receive multicast data from Source 1, and MVPN extranet enables Receiver 2 to receive multicast data from Source 1.

The MVPN extranet solution can be implemented through the source-PE-based MVPN extranet option or the receiver-PE-based MVPN extranet option.

Source-PE-based MVPN extranet option

To use this option, create a receiver VPN instance on the source PE and specify a default group for this VPN instance. The default group for the receiver VPN instance must be the same as the default group specified on other PEs in this VPN instance.

This option is available only in MDT-based MVPN.

As shown in Figure 2, perform the following tasks:

1.     For multicast traffic transmission from Site 1 to Site 2, configure MVPN for VPN A on PE 1 and PE 2.

2.     For multicast traffic transmission from Site 1 to Site 3, create VPN B and configure MVPN for VPN B on PE 1.

3.     Configure an MVPN extranet RPF selection policy for VPN B on PE 1.

Figure 2 Source-PE-based MVPN extranet option

 

When Receiver 2 in VPN B joins the multicast group that matches the policy, multicast packets from Source 1 are transmitted as follows:

1.     PE 1 replicates and encapsulates the packets for VPN A and VPN B and forwards them.

2.     The packets travel along default MDTs of VPN A and VPN B and arrive at PE 2 and PE 3.

3.     PE 2 and PE 3 decapsulate and forward the packets to receivers.

Receiver-PE-based MVPN extranet option

To use this option, create a source VPN instance on the receiver PE and specifies a default group for this VPN instance. The default group for the source VPN instance must be the same as the default group specified on other PEs in this VPN instance.

This option is available in MDT-based MVPN, RSVP-TE-based MVPN, and mLDP-based MVPN. This example uses MDT-based MVPN.

As shown in Figure 3, configure PEs as follows:

1.     For multicast traffic transmission from Site 1 to Site 2, configure MVPN for VPN A on PE 1 and PE 2.

2.     For multicast traffic transmission from Site 1 to Site 3, create VPN A and configure MVPN for VPN A on PE 3.

3.     Configure an MVPN extranet RPF selection policy for VPN B on PE 3.

Figure 3 Receiver-PE-based MVPN extranet option

 

When Receiver 2 in VPN B joins the multicast group that matches the RPF selection policy, multicast packets from Source 1 are encapsulated on PE 1 and transmitted along the default MDT.

1.     When the packets arrive at PE 2, PE 2 decapsulates the packets and forwards them to Receiver 1.

2.     When the packets arrive at PE 3, PE 3 decapsulates the packets and forwards them to Receiver 2 based on the MVPN extranet RPF selection policy.

Configuring an MVPN extranet RPF selection policy

About configuring MVPN extranet RPF selection policies

MVPN extranet RPF routing policies are used for multicast transmission when multicast sources and receivers are located in different VPNs.

Restrictions and guidelines for configuring MVPN extranet RPF selection policies

The PIM modes in the source VPN instance and the receiver VPN instance must be the same. Only PIM-SM and PIM-SSM are supported.

Multicast packets can only be forwarded between two VPNs. The receiver VPN instance cannot also be the source VPN instance.

In PIM-SM mode, you can configure only one RPF selection policy for a multicast group in a VPN instance.

If an MVPN extranet RPF selection policy is configured in the receiver VPN instance, the multicast traffic of the source group specified in the extranet RPF selection policy will be interrupted.

To implement source-specific RPF selection in MVPN extranet, you must configure two MVPN extranet RPF routing policies as follows:

·     In one policy, specify the address of the RP designated to the multicast group that requires inter-VPN multicast communication as the source address.

·     In the other policy, specify the multicast source in the source VPN instance as the source address.

To implement source-and-group-specific RPF selection in MVPN extranet, you must configure two MVPN extranet RPF routing policies as follows:

·     In one policy, specify the address of the RP designated to the multicast group as the source address, and specify the multicast group.

·     In the other policy, specify the multicast source in the source VPN instance as the source address, and specify the multicast group.

·     Make sure the multicast groups in the two policies are the same to avoid inter-VPN multicast transmission failure.

Only common Layer 3 multicast and MDT-based MVPN support the source-PE-based MVPN extranet option. Common Layer 3 multicast, MDT-based MVPN, RSVP-TE-based MVPN, mLDP-based MVPN, and BIER-based MVPN support the receiver-PE-based MVPN extranet option.

For the source-PE-based MVPN extranet option, if PIM-SM mode is used, the RP of the receiver VPN instance must be configured on the multicast source-side device.

Prerequisites for configuring MVPN extranet RPF selection policies

For the source-PE-based MVPN extranet option, configure MDT-based MVPN first. For more information, see "Configuring MDT-based MVPN."

For the receiver-PE-based MVPN extranet option, configure MDT-based, RSVP-TE-based, or mLDP-based MVPN first. For more information, see "Configuring MDT-based MVPN", "Configuring RSVP-TE-based MVPN", "Configuring mLDP-based MVPN", and "Configuring BIER-based MVPN."

Configuring an IPv4 MVPN extranet RPF selection policy

1.     Enter system view.

system-view

2.     Enter MRIB view.

3.     Configure an IPv4 MVPN extranet RPF selection policy.

multicast extranet select-rpf [ vpn-instance vpn-instance-name ] { source source-address { mask | mask-length } | group group-address { mask | mask-length } } *

By default, no IPv4 MVPN extranet RPF selection policies are configured.
