The network requirements for single-AS MD-VPN configuration are listed in the table below:  

Multicast sources 
and receivers 

z 

In VPN a, S 1 is a multicast source, and R 1, R 2 and R3 are receivers.  

z 

In VPN b, S 2 is a multicast source, and R 4 is a receiver.  

z 

For VPN a, the share-group address is 239.1.1.1. 

z 

For VPN b, the share-group address is 239.2.2.2. 

PE interfaces and 
VPN instances 
they belong to 

z 

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. 

z 

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.  

z 

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 

z 

Configure OSPF in the public network, and configure RIP between the PEs 
and CEs.  

z 

Establish BGP peer connections between PE 1, PE 2 and PE 3 on their 
respective Loopback 1 interface and exchange all private network routes 
between them.  

z 

Configure MPLS in the public network.  

IP multicast 
routing 

z 

Enable IP multicast routing on the P device.  

z 

Enable IP multicast routing in the public instance on PE 1, PE 2, and PE 3. 

z 

Enable IP multicast routing in VPN instance a on PE 1, PE 2, and PE 3.  

z 

Enable IP multicast routing in VPN instance b on PE 2 and PE 3.  

z 

Enable IP multicast routing on CE a1, CE a2, CE a3, CE b1, and CE b2.  

IGMP 

z 

Run IGMPv2 on VLAN-interface 20 of PE 1.  

z 

Run IGMPv2 on VLAN-interface 40 of CE a2, VLAN-interface 50 of CE a3, 
and VLAN-interface 60 of CE b2.
