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 address is 239.1.1.1, and the data-group
address range is 225.1.1.0 to 225.1.1.15.
• For VPN instance b, the default-group address is 239.4.4.4, and the data-group
address range is 225.4.4.0 to 225.4.4.15.
PE interfaces and
VPN instances to
which they 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, and exchange all VPN routes between them.
• 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 in VPN instance a on PE 1 and PE 4.
• Enable IP multicast routing in VPN instance b on PE 1 and PE 4.
• Enable IP multicast routing on CE a1, CE a2, CE b1, and CE b2.
IGMP
• Run IGMPv2 on VLAN-interface 30 of CE a2.
• Run IGMPv2 on VLAN-interface 40 of CE b2.
PIM
• 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 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.
