Example: Configuring intra-AS MDT-based MVPN

Network configuration

As shown in Figure 78, configure intra-AS MDT-based MVPN to meet the following requirements:

Item	Network configuration
Multicast sources and receivers	In VPN instance a, S 1 is a multicast source, and R 1, R 2 and R 3 are receivers. In VPN instance b, S 2 is a multicast source, and R 4 is a receiver. For VPN instance a, the default-group is 239.1.1.1, and the data-group range is 225.2.2.0 to 225.2.2.15. For VPN instance b, the default-group is 239.2.2, and the data-group range is 225.4.4.0 to 225.4.4.15.
VPN instances to which PE interfaces belong	PE 1: VLAN-interface 11 and VLAN-interface 20 belong to VPN instance a. VLAN-interface 12 and Loopback 1 belong to the public network instance. PE 2: VLAN-interface 13 belongs to VPN instance b. VLAN-interface 14 belongs to VPN instance a. VLAN-interface 15 and Loopback 1 belong to the public network instance. PE 3: VLAN-interface 17 belongs to VPN instance a. VLAN-interface 18 and Loopback 2 belong to VPN instance b. VLAN-interface 19 and Loopback 1 belong to the public network instance.
Unicast routing protocols and MPLS	Configure OSPF on the public network, and configure RIP between the PEs and CEs. Establish BGP peer connections between PE 1, PE 2, and PE 3 on their respective Loopback 1. Configure MPLS on the public network.
IP multicast routing	Enable IP multicast routing on the P device. Enable IP multicast routing on the public network on PE 1, PE 2, and PE 3. Enable IP multicast routing for VPN instance a on PE 1, PE 2, and PE 3. Enable IP multicast routing for VPN instance b on PE 2 and PE 3. Enable IP multicast routing on CE a1, CE a2, CE a3, CE b1, and CE b2.
IGMP	Enable IGMPv2 on VLAN-interface 20 of PE 1. Enable IGMPv2 on VLAN-interface 40 of CE a2, VLAN-interface 50 of CE a3, and VLAN-interface 60 of CE b2.
PIM	Enable PIM-SM on the public network and for VPN instances a and b: Enable PIM-SM on all interfaces of the P device. Enable PIM-SM on all public and private network interfaces of PE 1, PE 2, and PE 3. Enable PIM-SM on all interfaces that have no receiver hosts connected of CE a1, CE a2, CE a3, CE b1, and CE b2. Configure Loopback 1 of P as a C-BSR and a C-RP for the public network to provide services for all multicast groups. Configure Loopback 1 of CE a2 as a C-BSR and a C-RP for VPN instance a to provide services for all multicast groups. Configure Loopback 2 of PE 3 as a C-BSR and a C-RP for VPN instance b to provide services for all multicast groups.
