MSDP Establish an MSDP peering relationship between PE 2 and PE 3 on their Loopback 1.
PE 1: GigabitEthernet 2/1/2 belongs to VPN instance a. GigabitEthernet 2/1/3
belongs to VPN instance b. GigabitEthernet 2/1/1 and Loopback 1 belong to the
public network instance.
PE 2: GigabitEthernet 2/1/1, GigabitEthernet 2/1/2, Loopback 1, and Loopback 2
belong to the public network instance.
PE 3: GigabitEthernet 2/1/1, GigabitEthernet 2/1/2, Loopback 1, and Loopback 2
belong to the public network instance.
PE 4: GigabitEthernet 2/1/2 belongs to VPN instance a. GigabitEthernet 2/1/3
belongs to VPN instance b. GigabitEthernet 2/1/1 and Loopback 1 belong to the
public network instance.
Configure OSPF separately in AS 100 and AS 200, and configure OSPF between
the PEs and CEs.
Establish BGP peer connections between PE 1, PE 2, PE 3, and PE 4 on their
respective Loopback 1, and exchange all VPN routes between them.
Configure MPLS separately in AS 100 and AS 200.
Enable IP multicast routing on the public network on PE 1, PE 2, PE 3, and PE 4.
Enable IP multicast routing in VPN instance a on PE 1 and PE 4.
Enable IP multicast routing in VPN instance b on PE 1 and PE 4.
Enable IP multicast routing on CE a1, CE a2, CE b1, and CE b2.
Run IGMPv2 on GigabitEthernet 2/1/1 of CE a2.
Run IGMPv2 on GigabitEthernet 2/1/1 of CE b2.
Enable PIM-SM on all public network interfaces of PE 2 and PE 3.
Enable PIM-SM on all public and private network interfaces of PE 1 and PE 4.
Enable PIM-SM on all interfaces that do not have attached receiver hosts on CE a1,
CE a2, CE b1, and CE b2.
Configure Loopback 2 of PE 2 and PE 3 as a C-BSR and a C-RP for their own AS to
provide services for all multicast groups.
Configure Loopback 0 of CE a1 as a C-BSR and a C-RP for VPN instance a to provide
services for all multicast groups.
Configure Loopback 0 of CE b1 as a C-BSR and a C-RP for VPN instance b to provide
services for all multicast groups.
