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

Network configuration

As shown in Figure 81, configure MDT-based MVPN inter-AS option C 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 239.1.1.1, and the data-group range is 225.1.1.0 to 225.1.1.15. For VPN instance b, the default-group is 239.4.4.4, and the data-group range is 225.4.4.0 to 225.4.4.15.
VPN instances to which PEs belong	PE 1: VLAN-interface 11 belongs to VPN instance b. VLAN-interface 12 belongs to VPN instance a. VLAN-interface 2 and Loopback 1 belong to the public network instance. PE 2: VLAN-interface 2, VLAN-interface 3, Loopback 1, and Loopback 2 belong to the public network instance. PE 3: VLAN-interface 3, VLAN-interface 4, Loopback 1, and Loopback 2 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 4 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 BGP peer connections between PE 1, PE 2, PE 3, and PE 4 on their respective Loopback 1. Configure MPLS separately in AS 100 and AS 200.
IP multicast routing	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.
IGMPv2	Enable IGMPv2 on VLAN-interface 30 of CE a2. Enable IGMPv2 on VLAN-interface 40 of CE b2.
PIM-SM	Enable PIM-SM on the public network and for VPN instances a and b: 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 of CE a1, CE a2, CE b1, and CE b2. Configure Loopback 2 of PE 2 and PE 3 as a C-BSR and a C-RP for their own AS to provide services for all multicast groups. Configure Loopback 0 of CE a1 as a C-BSR and a C-RP for VPN instance a to provide services for all multicast groups. Configure Loopback 0 of CE b1 as a C-BSR and a C-RP for VPN instance b to provide services for all multicast groups.
MSDP	Establish an MSDP peering relationship between PE 2 and PE 3 on their Loopback 1.
