Configuration Roadmap
The configuration roadmap is as follows:

Requirements
The multicast source of VPN-RED is Source 1; the receivers of VPN-
RED are PC1, PC2, and PC3. The multicast source of VPN-BLUE is
Source 2 and the receiver of VPN-BLUE is PC4. The Share-Group
address of VPN-RED is 239.1.1.1; the addresses in the Switch-Group
address pool range from 225.2.2.1 to 225.2.2.16. The Share-Group
address of VPN-BLUE is 239.2.2.2; the addresses in the Switch-Group
address pool range from 225.4.4.1 to 225.4.4.16.
GE2 and GE3 on PE-A belong to the VPN-RED instance; GE1 and
Loopback 1 on PE-A belong to the public network instance; GE2 on
PE-B belongs to the VPN-BLUE instance; GE3 on PE-B belongs to
the VPN-RED instance; GE1 and Loopback 1 on PE-B belong to the
public network instance; GE2 on PE-C belongs to the VPN-RED
instance; GE3 and Loopback 2 on PE-C belong to the VPN-BLUE
instance; GE1 and Loopback 1 on PE-C belong to the public network
instance.
OSPF is configured on the public network; RIP is configured between
PEs and switches (CEs). BGP peer connections are set up between the
Loopback 1 interfaces on PE-A, PE-B, and PE-C. All private network
routes are transmitted along these BGP peer connections. MPLS
forwarding starts on the public network.
Multicast is enabled on the P. Multicast is enabled on the public
network instances of PE-A, PE-B, and PE-C. Multicast is enabled on
the VPN-RED instances of PE-A, PE-B, and PE-C. Multicast is
enabled on the VPN-BLUE instances of PE-B and PE-C. Multicast is
enabled on CE-Ra, CE-Rb, CE-Rc, CE-Bb, and CE-Bc.
IGMP is enabled on GE2 on PE-A, GE1 interfaces of CE-Rb, CE-Rc,
CE-Bb, and CE-Bc.
PIM-SM is enabled on all the private network interfaces of VPN-RED
and VPN-BLUE. PIM-SM is enabled on all the interfaces of Ps and
CEs, and on all the public network interfaces of PEs. Loopback 1 of
the P acts as a C-BSR and C-RP for all the groups. Loopback 1 of the
CE-Rb acts as the C-BSR and C-RP for the private network VPN-RED
for all the groups. Loopback 2 of PE-C acts as the C-BSR and C-RP
for the private network VPN-BLUE for all the groups.
Configure MPLS/BGP VPN; ensure that the VPN works normally and unicast routes are
reachable.
On the PE, configure Eth-Trunk 10 as the multicast loopback interface.
