我需要源特定多播实现说明
我阅读了文档：
http://www.ietf.org/rfc/rfc3569.txt

我很困惑关于SSM、SFM、ASM API的使用！
据我了解，IGMPv3 包含模式应仅适用于 SSM IP 地址范围 (232/8)。不是 ASM IP 范围。据我了解，排除模式应仅适用于 ASM IP 地址范围。不是 SSM IP 范围。然而，正如 RFC 3569 所说：“请注意，IGMPv3/MLDv2 并不将 (S,G) 加入限制为仅 232/8 范围。但是，如 [RFC 4607] 中定义的 SSM 服务仅在此地址范围内可用IPv4。” （作为旁注，我相信可以设置一些路由器，以便 SSM 适用于整个多播范围）
然而，根据 RFC 3569，SFM 似乎适用于整个 ASM IP 范围，并且会使用包含模式和排除模式 API，其中似乎与我之前的假设相矛盾。
因此，我的问题是，如果我的网络支持 IGMPv3，我可以在哪个多播 IP 地址范围内使用包含和排除模式 API？
I read document:
http://www.ietf.org/rfc/rfc3569.txt
I also had a look at
I am confused regarding SSM Vs SFM Vs ASM API to use!
It is my understanding that the IGMPv3 Include Mode should apply only to the SSM IP address range (232/8). Not the ASM IP range. It is also my understanding that the Exclude Mode should apply only to the ASM IP address range. Not the SSM IP range. Yet as RFC 3569 say : "Note that IGMPv3/MLDv2 does not limit (S,G) joins to only the 232/8 range. However, SSM service, as defined in [RFC 4607], is available only in this address range for IPv4." (As a side note I believe it is possible to setup some Routers such that SSM apply to the full multicast range)
Yet according to RFC 3569 SFM seems to apply to the whole ASM IP range and would use both Include mode and Exclude mode API which seems to contradict my previous assumption.
Thus my question is with which Multicast IP address range can I use the Include and Exclude mode API if my networking supports IGMPv3?

API 允许您使用任何地址，同样，路由器可以配置为使用 SSM 和 ASM 的任何地址。然而，RFC 详细介绍了如果您想通过 Internet 进行路由（即通过使用标准通用配置的第三方）的建议步骤。
那么你的问题没有足够的上下文，IP 堆栈关心你不需要的 IGMP/MLD。唯一值得关注的领域甚至不是开发人员，而应该是选择部署地址的管理员。
The APIs allow you to use any addresses, similarly routers can be configured to use any addresses for SSM and ASM. However the RFC details the recommended steps for if you want to route over the Internet, i.e. through third parties using a standard common configuration.
Then you question doesn't have enough context, it is the IP stack that cares about IGMP/MLD you don't need to. The only area of concern is not even the developer it should be the administrators selecting addresses for deployment.
