Multicast VPN configuration examples
This section provides examples of configuring multicast VPN on switches.
Intra-AS MD VPN configuration example
Network requirements
As shown in
, configure intra-AS MD VPN to meet the following requirements:
Item
Network requirements
Multicast sources
and receivers
•
In VPN instance
a
, S 1 is a multicast source, and R 1, R 2 and R 3 are receivers.
•
In VPN instance
b
, S 2 is a multicast source, and R 4 is a receiver.
•
For VPN instance
a
, the default-group is 239.1.1.1, and the data-group range is
225.2.2.0 to 225.2.2.15.
•
For VPN instance
b
, the default-group is 239.2.2, and the data-group range is
225.4.4.0 to 225.4.4.15.
VPN instances to
which PE interfaces
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.
•
Configure MPLS on 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 for VPN instance
a
on PE 1, PE 2, and PE 3.
•
Enable IP multicast routing for 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
•
Enable IGMPv2 on VLAN-interface 20 of PE 1.
