Example for Configuring an NG MVPN (PIM-SM MDT Setup Across the Public Network) with (*, G) Join to Carry Multicast Traffic over an RSVP-TE P2MP LSP

This section provides an example for configuring an NG MVPN (PIM-SM MDT setup across the public network) with (*, G) Join to carry multicast traffic over an RSVP-TE P2MP LSP.

Networking Requirements

On the network shown in Figure 1, RSVP-TE tunnels have been deployed to carry BGP/MPLS IP VPN services. In this example, users send PIM-SM (*, G) Join messages to join a multicast group. Configure PIM-SM MDTs to be set up across the public network.

Figure 1 Intra-AS NG MVPN networking

Interfaces 1, 2, and 3 in this example represent GE 0/1/0, GE 0/1/1, and GE 0/1/2, respectively.

Configuration Roadmap

The configuration roadmap is as follows:

Configure BGP/MPLS IP VPN and ensure that unicast VPN services are properly transmitted.
Enable P2MP TE globally and configure a P2MP TE template on each PE so that the PEs can use RSVP-TE to establish a P2MP LSP.
Establish BGP MVPN peer relationships between the PEs so that the PEs can use BGP to exchange BGP A-D and BGP C-multicast routes (C is short for Customer. C-multicast refers to multicast routes from the CE).
Configure PE1 to use RSVP-TE to establish an I-PMSI tunnel so that an RSVP-TE P2MP LSP can be triggered. Configure PIM-SM MDTs to be set up across the public network.
Configure PIM-SM on the PE interfaces bound to VPN instances and on the CE interfaces connecting to PEs to allow a VPN multicast routing table to be established to guide multicast traffic forwarding.
Configure a static RP for a VPN instance.

In an NG MVPN scenario, if PIM-SM MDT setup is across the public network and triggered by (*, G) Join messages, only static RPs can be used. Either a PE or CE can be configured as an RP.
Configure IGMP on the interfaces connecting a multicast device to a user network segment to allow the device to manage multicast group members on the network segment.

Data Preparation

To complete the configuration, you need the following data:

Loopback1 interface addresses of PE1, PE2, PE3, and CE3 (1.1.1.1, 2.2.2.2, 3.3.3.3, and 4.4.4.4)
OSPF process on the public network (process 1) in Area 0; OSPF multi-process (process 2) in Area 0
MPLS LSR IDs of PE1, PE2, and PE3 (1.1.1.1, 2.2.2.2, and 3.3.3.3)
AS number of PEs (AS 100)
MVPN IDs of PE1, PE2, and PE3 (1.1.1.1, 2.2.2.2, and 3.3.3.3)
VPN instance names (VPN A), RDs (100:1, 200:1, and 300:1), and VPN targets of VPN instances (3:3)

Procedure

Configure BGP/MPLS IP VPN.

Configure the VPN backbone network and the IP address of each interface in each VPN site.
Assign an IP address to each interface according to Figure 1. For configuration details, see Configuration Files in this section.
Configure an IGP to interconnect devices on the BGP/MPLS IP VPN backbone network.
OSPF is used in this example. For configuration details, see Configuration Files in this section.

To use OSPF in an RSVP-TE P2MP LSP scenario, you must configure IGP TE (OSPF or IS-IS).

Configure basic MPLS functions and enable MPLS TE to establish MPLS TE tunnels on the MPLS backbone network.

Verify the configuration.

After the configurations are complete, an NG MVPN with (*, G) join is configured. In this example, multicast source (10.1.3.0/24) in the PIM-SM domain sends multicast traffic to multicast group G (225.0.0.1). The receiver joins multicast group G and receives multicast traffic from this group. Run the display pim routing-table command to check whether multicast routing entries are correctly generated and whether the NG MVPN with (*, G) join is successfully configured.

Run the display pim vpn-instance routing-table command on the PEs to check the PIM routing tables of VPN A.

The command output shows that PE2 connected to the RP has received a Join message from PE3 connected to a receiver, created a (*, G) entry, and implemented a switchover from an RPT to an SPT. (S, G) PIM routing entries have been created successfully, and the receiver can receive multicast data from the multicast source 10.1.3.100.

Run the display mvpn vpn-instance vpn-instance-name ipmsi verbose command on the PEs to check I-PMSI tunnel establishment. The following example uses the command output on PE3:

[~PE3] display mvpn vpn-instance VPNA ipmsi verbose
MVPN local I-PMSI information for VPN-Instance: VPNA
Tunnel type: RSVP-TE P2MP LSP
Tunnel state: --
P2MP ID: 0x1010101
Tunnel ID: 32769
Extended tunnel ID: 1.1.1.1
Root: 1.1.1.1
Leaf:
  1: 3.3.3.3 (local)
Total number of (S, G): 1
    1. (10.1.3.100, 225.0.0.1)

Tunnel type: RSVP-TE P2MP LSP
Tunnel state: --
P2MP ID: 0x2020202
Tunnel ID: 32769
Extended tunnel ID: 2.2.2.2
Root: 2.2.2.2
Leaf:
  1: 3.3.3.3 (local)

The command outputs show that two RSVP-TE P2MP LSPs have been established, with PE1 and PE2 as the root nodes respectively and PE3 as the leaf node.
