Example for Configuring Single-AS MD VPNs

This section provides an example for configuring single-AS multicast domain (MD) VPN on an MPLS/BGP network to enable the transmission of multicast data of private networks over a public network to receivers.

Networking Requirements

In the single-AS MPLS/BGP VPN shown in Figure 1, configure MD to deploy multicast services.

Figure 1 Configuring single-AS MD VPNs

The networking requirements are described in Table 1:

Table 1 Networking requirements of single-AS MD VPNs

Item

Networking Requirements

Multicast source/receiver

The multicast source of VPN RED is Source 1. The receivers include PC1, PC2, and PC3. The multicast source of VPN BLUE is Source 2. The receiver is PC4. In the VPN RED, the Share-Group address is 239.1.1.1 and Switch-Group pool address ranges from 225.2.2.1 to 225.2.2.16. In the VPN BLUE, the Share-Group address is 239.2.2.2 and Switch-Group pool address ranges from 225.4.4.1 to 225.4.4.16.

VPN instance to which the interfaces on PEs belong

On PE-A, GE2 and GE3 belong to VPN-RED, and GE1 and Loopback1 belong to the public network instance. On PE-B, GE2 belongs to VPN-BLUE, GE3 belongs to VPN-RED, and GE1 and Loopback1 belong to the public network instance. On PE-C, GE2 belongs to VPN-RED, GE3 and Loopback2 belong to VPN-BLUE, and GE1 and Loopback1 belong to the public network instance.

Routing protocol and MPLS

Configure Open Shortest Path First (OSPF) on the public network. Enable the Routing Information Protocol (RIP) on PE and CE devices. Establish BGP peer relationships and transmit all private network routes between Loopback1 interfaces on PE-A, PE-B, and PE-C. Enable MPLS forwarding on the public network.

Multicast function

Enable multicast on the P. Enable multicast on the public network instance on PE-A, PE-B, and PE-C. Enable multicast on the VPN-RED on PE-A, PE-B, and PE-C. Enable multicast on the VPN-BLUE on PE-B and PE-C. Enable multicast on CE-Ra, CE-Rb, CE-Rc, CE-Bb, and CE-Bc.

IGMP function

Enable the Internet Group Management Protocol (IGMP) on GE2 of PE-A. Enable IGMP on GE1 interfaces of CE-Rb, CE-Rc, and CE-Bc.

PIM function

Enable PIM-SM on all the VPN interfaces in VPN-RED. Enable PIM-SM on all the VPN interfaces in VPN-BLUE. Enable PIM-SM on all the interfaces of the P and CEs, and the public network interfaces of PEs. Configure Loopback1 on the P as the Candidate-BootStrap Router (C-BSR) and Candidate-Rendezvous Point (C-RP) of the public network (serving all multicast groups). Configure Loopback1 on CE-Rb as the C-BSR and C-RP of VPN-RED (serving all multicast groups). Configure Loopback2 on PE-C as the C-BSR and C-RP of VPN-BLUE (serving all multicast groups).

Based on the networking requirements, IP addresses of the interfaces in Figure 1 are shown in Table 2.

In this example, GE1 stands for GE 0/1/0, GE2 stands for GE 0/1/8, and GE3 stands for GE 0/1/16.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure MPLS/BGP VPN to ensure that the VPN network works properly and unicast routes are reachable.

  2. Enable multicast routing and PIM on the entire network. Enable public network instance multicast on the PEs and P, and enable VPN instance multicast with the IPv4 address family on PEs and CEs.

  3. Configure the same share-group address, the same MTI, and the same switch-group-pool range of a switch-MDT for the same VPN instance enabled with the IPv4 address family on each PE. Set the automatic configuration mode for the MTI.

Data Preparation
