Multicast VPN configuration examples
IMPORTANT:
By default, Ethernet interfaces, VLAN interfaces, and aggregate interfaces are in the state of DOWN. To
configure such an interface, use the undo shutdown command to bring it up first.

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, and the switch-group-pool address
range is 225.2.2.0 to 225.2.2.15.
•
For VPN b, the share-group address is 239.2.2.2, and the switch-group-pool address
range is 225.4.4.0 to 225.4.4.15.
PE interfaces and
VPN instances to
which they belong
•
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 on 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 on the public network.
