Network requirements

Item Network re

uirements

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.

• For VPN instance b, the default-group address is 239.2.2.2.

PE interfaces and VPN

instances to which they belong

• PE 1: Ethernet 1/2 and Ethernet 1/3 belong to VPN instance a. Ethernet

1/1 and Loopback 1 belong to the public network.

• PE 2: Ethernet 1/2 belongs to VPN instance b. Ethernet 1/3 belongs to

VPN instance a. Ethernet 1/1 and Loopback 1 belong to the public

network.

• PE 3: Ethernet 1/2 belongs to VPN instance a. Ethernet 1/3 and

Loopback 2 belongs to VPN instance b. Ethernet 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 Ethernet 1/2 of PE 1.

• Run IGMPv2 on Ethernet 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 of PE 1, PE 2,

and PE 3.

• Enable PIM-SM on all interfaces of 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.
