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 address is 239.1.1.1, and the
data-group address range is 225.2.2.0 to 225.2.2.15.
• For VPN instance b, the default-group address is 239.2.2.2, 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: GigabitEthernet 2/1/2 and GigabitEthernet 2/1/3 belong to VPN
instance a. GigabitEthernet 2/1/1 and Loopback 1 belong to the public
network.
• PE 2: GigabitEthernet 2/1/2 belongs to VPN instance b. GigabitEthernet
2/1/3 belongs to VPN instance a. GigabitEthernet 2/1/1 and Loopback
1 belong to the public network.
• PE 3: GigabitEthernet 2/1/2 belongs to VPN instance a. GigabitEthernet
2/1/3 and Loopback 2 belongs to VPN instance b. GigabitEthernet
2/1/1 and Loopback 1 belong to the public network.
Unicast routing protocols and
MPLS
• Configure OSPF on the public network, and configure RIP between the PE
devices and the CE devices.
• Establish BGP peer connections between PE 1, PE 2, and PE 3 on their
respective Loopback 1, and exchange all VPN routes between them.
• Configure MPLS on the public network.
IP multicast routing
• Enable IP multicast routing on the P router.
• Enable IP multicast routing on the public network instance on PE 1, PE 2,
and PE 3.
• Enable IP multicast routing in VPN instance a on PE 1, PE 2, and PE 3.
• Enable IP multicast routing in 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
• Run IGMPv2 on GigabitEthernet 2/1/2 of PE 1.
• Run IGMPv2 on GigabitEthernet 2/1/1 of CE a2, CE a3, and CE b2.
PIM
• Enable PIM-SM on all interfaces of the P router.
• Enable PIM-SM on all public and private network interfaces that do not
have attached receiver hosts on PE 1, PE 2, and PE 3.
• Enable PIM-SM on all interfaces that do not have attached receiver hosts
on CE a1, CE a2, CE a3, CE b1, and CE b2.
• Configure Loopback 1 of P as a public network C-BSR and C-RP 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.
