In VPN a, S 1 is the multicast source, and R 1, R 2 and R 3 are
receivers
In VPN a, S 2 is the multicast source, and R 4 is a receiver
Of VPN a, the share-group address is 239.1.1.1, and the address
range of its switch-group-pool is 225.2.2.0 to 225.2.2.15
Of VPN b, the share-group address is 239.2.2.2, and the address
range of its switch-group-pool is 225.4.4.0 to 225.4.4.15
PE 1: Ethernet 0/2 and Ethernet 0/3 belong to VPN instance a;
Ethernet 0/1 and Loopback 1 belong to the public instance
PE 2: Ethernet 0/2 belongs to VPN instance b; Ethernet 0/3 belongs
to VPN instance a; Ethernet 0/1 and Loopback 1 belong to the
public instance
PE 3: Ethernet 0/2 belongs to VPN instance a; Ethernet 0/3 and
Loopback 2 belongs to VPN instance b; Ethernet 0/1 and Loopback
1 belong to the public instance
Configure OSPF in 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 via
their respective Loopback 1 interface and exchange routing
information between all private networks
Configure MPLS in the public network
Enable IP multicast routing on the P router
Enable IP multicast routing in the public 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
Enable IGMP on Ethernet 0/2 of PE 1
Enable IGMP on Ethernet 0/1 of CE a2, CE a3, and CE b2
Enable PIM-SM on all interfaces of the P router
Enable PIM-SM on all public network interfaces and private network
interface 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
work for all multicast groups)
Configure Loopback 1 of CE a2 as a C-BSR and C-RP for VPN a (to
work for all multicast groups)
Configure Loopback 2 of PE 3 as a C-BSR and C-RP for VPN b (to
work for all multicast groups)
