本文档介绍组播VPN的典型配置举例。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解组播VPN特性。
如图1所示，Customer A有位于两地的分支机构，这两个分支机构已通过同一个运营商的MPLS L3VPN网络实现了两地间单播路由信息的正常交互。目前Customer A中的组播源与接收者分别位于不同的分支机构中，且各分支机构内运行的PIM协议模式为PIM-SM。现要求通过MDT模式MVPN技术，实现组播接收者能够正常接收到组播源发来的组播数据。

为了实现上述组网需求，需要在公网的各设备上运行PIM协议（与私网中的PIM协议模式相互独立），并在各PE设备上配置MDT模式MVPN。
· 配置MDT模式MVPN时，只有在指定了Default-Group和MVPN源接口，并获取到MVPN源接口的公网IP地址之后，MTI才会生效。此外，还必须先使用service-loopback group命令创建Multicast tunnel类型的业务环回组，MTI才能正常转发。有关service-loopback group命令的详细介绍，请参见《H3C S12500G-AF系列交换机 二层技术-以太网交换命令参考》。
· 属于同一VPN的所有接口（包括PE上绑定VPN实例的接口）上必须运行相同模式的PIM协议。
· 在不同的PE上，应该为相同MDT模式MVPN实例指定相同的Default-Group。
· MVPN源接口必须与建立BGP对等体时所使用的源接口相同，否则将无法获取正确的路由信息。
# 按照图1配置各设备上的接口IP地址和子网掩码。

如图2所示，Customer A有位于两地的分支机构，这两个分支机构跨越了两个运营商网络，并已通过跨域VPN-OptionA方案实现了两地间单播路由信息的正常交互。目前Customer A中的组播源与接收者分别位于不同的分支机构中，且各分支机构内运行的PIM协议模式为PIM-SM。现要求通过MDT模式MVPN技术，实现组播接收者能够正常接收到组播源发来的组播数据。

为了实现上述组网需求，需要在每个AS内各建立一个独立的MDT模式MVPN实例。
· 各AS内部运行的公网PIM模式可以不同，但属于同一VPN的所有接口（包括ASBR上绑定VPN实例的接口）上必须运行统一的PIM模式。
· 对于同一AS内的相同MDT模式MVPN实例，应为其指定相同的Default-Group，对于不同AS的相同VPN实例，为其MDT模式MVPN实例指定的Default-Group可以不同。
# 按照图2配置各设备上的接口IP地址和子网掩码。

如图3所示，Customer A有位于两地的分支机构，这两个分支机构跨越了两个运营商网络，并已通过跨域VPN-OptionC方案实现了两地间单播路由信息的正常交互。目前Customer A中的组播源与接收者分别位于不同的分支机构中，且各分支机构内运行的PIM协议模式为PIM-SM。现要求通过MDT模式MVPN技术，实现组播接收者能够正常接收到组播源发来的组播数据。

· 为了实现上述组网需求，需要在所有AS内统一建立一个MDT模式MVPN实例。
· 为了使公网PIM-SM域之间组播源信息的共享，需要在各公网PIM-SM域的RP之间建立MSDP对等体。
# 按照5.1 图3配置各设备上的接口IP地址和子网掩码。

# 按照如上配置后，通过在PE及ASBR-PE设备上执行display pim routing-table命令，可以检查公网Default-MDT建立情况，以ASBR-PE 1设备为例：
[ASBR-PE1]display pim routing-table
Total 1 (*, G) entries; 2 (S, G) entries
(*, 239.1.1.1)
RP: 3.3.3.3 (local)
Protocol: pim-sm, Flag: SPT LOC ACT
UpTime: 02:54:43
Upstream interface: Register
Upstream neighbor: NULL
RPF prime neighbor: NULL
Downstream interface(s) information:
Total number of downstreams: 1
1: Vlan-interface2
Protocol: pim-sm, UpTime: 02:54:43, Expires: -
(1.1.1.1, 239.1.1.1)
RP: 3.3.3.3 (local)
Protocol: pim-sm, Flag: SPT LOC ACT
UpTime: 01:57:13
Upstream interface: Vlan-interface2
Upstream neighbor: 192.168.1.2
RPF prime neighbor: 192.168.1.2
Downstream interface(s) information: None
(1.1.1.4, 239.1.1.1)
RP: 3.3.3.3 (local)
Protocol: pim-sm, Flag: SPT LOC ACT
UpTime: 01:57:13
Upstream interface: Vlan-interface3
Upstream neighbor: 192.168.2.2
RPF prime neighbor: 192.168.2.2
Downstream interface(s) information: None
由此可见，公网ASBR-PE 1设备上已建立RPT（*，239.1.1.1）和两棵相互独立的SPT树，这三棵树共同组成了该公网MDT模式MVPN实例上的Default-MDT。
