Multicast VPN configuration examples
This section provides examples of configuring multicast VPN on routers.
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 239.2.2.2, and the
data-group range is 225.4.4.0 to 225.4.4.15.
VPN instances to which PE
interfaces belong
•
PE 1: GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 belong to VPN
instance
a
. GigabitEthernet 1/0/1 and Loopback 1 belong to the public
network.
•
PE 2: GigabitEthernet 1/0/2 belongs to VPN instance
b
.
GigabitEthernet 1/0/3 belongs to VPN instance
a
. GigabitEthernet
1/0/1 and Loopback 1 belong to the public network.
•
PE 3: GigabitEthernet 1/0/2 belongs to VPN instance
a
.
GigabitEthernet 1/0/3 and Loopback 2 belongs to VPN instance
b
.
GigabitEthernet 1/0/1 and Loopback 1 belong to the public network.
Unicast routing protocols and
MPLS
•
Configure OSPF on the public network, and configure RIP between
the PE devices and the CE devices.
•
Establish BGP peer connections between PE 1, PE 2, and PE 3 on
their respective Loopback 1.
•
Configure MPLS on the public network.
