Multicast sources and receivers
• In VPN a, S 1 is a multicast source, and R 1, R 2 and R 3 are receivers.
• In VPN b, S 2 is a multicast source, and R 4 is a receiver.
• For VPN a, the share-group address is 239.1.1.1, and the range of its
switch-group-pool addresses is 225.2.2.0 to 225.2.2.15.
• For VPN b, the share-group address is 239.2.2.2, and the range of its
switch-group-pool addresses is 225.4.4.0 to 225.4.4.15.
PE interfaces and VPN
instances they belong to
• 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 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.
