requirements
Multicast sources
and receivers
•
In VPN a, S 1 is a multicast source, and R 1, R 2 and R3 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.
•
For VPN b, the share-group address is 239.2.2.2.
PE interfaces and
VPN instances they
belong to
•
PE 1: VLAN-interface 11 and VLAN-interface 20 belong to VPN instance a.
VLAN-interface 12 and Loopback 1 belong to the public network instance.
•
PE 2: VLAN-interface 13 belongs to VPN instance b; VLAN-interface 14 belongs
to VPN instance a. VLAN-interface 15 and Loopback 1 belong to the public
network instance.
•
PE 3: VLAN-interface 17 belongs to VPN instance a. VLAN-interface 18 and
Loopback 2 belong to VPN instance b. VLAN-interface 19 and Loopback 1
belong to the public network instance.
Unicast routing
protocols and
MPLS
•
Configure OSPF in the public network, and configure RIP between the PEs and
CEs.
•
Establish BGP peer connections between PE 1, PE 2 and PE 3 on their
respective Loopback 1 interface and exchange all VPN routes between them.
•
Configure MPLS in the public network.
IP multicast routing
•
Enable IP multicast routing on the P device.
•
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 VLAN-interface 20 of PE 1.
•
Run IGMPv2 on VLAN-interface 40 of CE a2, VLAN-interface 50 of CE a3, and
VLAN-interface 60 of CE b2.
PIM
•
Enable PIM-SM on all interfaces of the P device.
•
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 C-BSR and a C-RP for the public network (to
work for all multicast groups).
•
Configure Loopback 1 of CE a2 as a C-BSR and a C-RP for VPN a (to work for all
