Multicast VPN Configuration Examples
Single-AS MD VPN Configuration
Network requirements
The network requirements for single-AS MD-VPN configuration are listed in the table below:
Item Network requirements
Multicast sources
and receivers
z
In VPN a, S 1 is a multicast source, and R 1, R 2 and R3 are receivers.
z
In VPN b, S 2 is a multicast source, and R 4 is a receiver.
z
For VPN a, the share-group address is 239.1.1.1.
z
For VPN b, the share-group address is 239.2.2.2.
PE interfaces and
VPN instances
they belong to
z
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.
z
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.
z
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
z
Configure OSPF in the public network, and configure RIP between the PEs
and CEs.
z
Establish BGP peer connections between PE 1, PE 2 and PE 3 on their
respective Loopback 1 interface and exchange all private network routes
between them.
z
Configure MPLS in the public network.
IP multicast
routing
z
Enable IP multicast routing on the P device.
z
Enable IP multicast routing in the public instance on PE 1, PE 2, and PE 3.
z
Enable IP multicast routing in VPN instance a on PE 1, PE 2, and PE 3.
z
Enable IP multicast routing in VPN instance b on PE 2 and PE 3.
z
Enable IP multicast routing on CE a1, CE a2, CE a3, CE b1, and CE b2.
IGMP
z
Run IGMPv2 on VLAN-interface 20 of PE 1.
z
Run IGMPv2 on VLAN-interface 40 of CE a2, VLAN-interface 50 of CE a3,
and VLAN-interface 60 of CE b2.
