Example: Configuring MDT-based MVPN inter-AS option B

Network configuration

As shown in Figure 80, configure MDT-based MVPN inter-AS option B to meet the following requirements:

Item	Network configuration
Multicast sources and receivers	In VPN instance a, S 1 is a multicast source, and R 2 is a receiver. In VPN instance b, S 2 is a multicast source, and R 1 is a receiver. For VPN instance a, the default-group is 232.1.1.1, and the data-group range is 232.2.2.0 to 232.2.2.15. They are in the SSM group range. For VPN instance b, the default-group is 232.3.3.3, and the data-group range is 232.4.4.0 to 232.4.4.15. They are in the SSM group range.
VPN instances to which PE interfaces belong	PE 1: VLAN-interface 11 belongs to VPN instance a. VLAN-interface 12 belongs to VPN instance b. VLAN-interface 2 and Loopback 1 belong to the public network instance. PE 2: VLAN-interface 3, VLAN-interface 4, and Loopback 1 belong to the public network instance. PE 3: VLAN-interface 4, VLAN-interface 5, and Loopback 1 belong to the public network instance. PE 4: VLAN-interface 13 belongs to VPN instance a. VLAN-interface 14 belongs to VPN instance b. VLAN-interface 6 and Loopback 1 belong to the public network instance.
Unicast routing protocols and MPLS	Configure OSPF separately in AS 100 and AS 200, and configure OSPF between the PEs and CEs. Establish IBGP peer connections between PE 1, PE 2, PE 3, and PE 4 on their respective Loopback 1. Configure BGP MDT peer connections between PE 1, PE 2, PE 3, and PE 4 on their respective Loopback 1 and between PE 2 and PE 3 on their respective VLAN-interface 4. Establish EBGP peer connections between VLAN-interface 4 on PE 2 and PE 3. Configure MPLS separately in AS 100 and AS 200.
IP multicast routing	Enable IP multicast routing on P 1 and P 2. Enable IP multicast routing on the public network on PE 1, PE 2, PE 3, and PE 4. Enable IP multicast routing for VPN instance a on PE 1 and PE 4. Enable IP multicast routing for VPN instance b on PE 1 and PE 4. Enable IP multicast routing on CE a1, CE a2, CE b1, and CE b2.
IGMP	Enable IGMPv2 on VLAN-interface 23 of CE a2. Enable IGMPv2 on VLAN-interface 24 of CE b2.
PIM	Enable PIM-SSM on the public network and PIM-SM on VPN instances a and b: Enable PIM-SM on all interfaces of P 1 and P 2. Enable PIM-SM on all public network interfaces of PE 2 and PE 3. Enable PIM-SM on all public and private network interfaces of PE 1 and PE 4. Enable PIM-SM on all interfaces that do not have attached receiver hosts on CE a1, CE a2, CE b1, and CE b2. Configure VLAN-interface 11 of CE a1 as a C-BSR and a C-RP for VPN instance a to provide services for all multicast groups. Configure VLAN-interface 12 of CE b1 as a C-BSR and a C-RP for VPN instance b to provide services for all multicast groups.
RPF vector	Enable the RPF vector feature on PE 1 and PE 4.
