SCTP多宿主初始化消息

在SCTP多主配置中，我配置了两组-主路径和辅助路径。我的问题是，默认情况下，INIT命令在主路径或辅助路径上发送到哪里（假设两条路径都已启动）？

---

是否存在仅在主路径处于启动状态时才需要在主路径上发送INIT的条件？

默认情况下，任何SCTP数据包都应使用主路径发送。这是我在RFC 4960中发现的-第6.4节-第三段

By default, an endpoint SHOULD always transmit to the primary path,
unless the SCTP user explicitly specifies the destination transport
address (and possibly source transport address) to use.

关于第二个问题-“是否存在仅当INIT处于启动状态时才需要在主路径上发送INIT的条件？”

通过关闭的接口发送看起来不符合逻辑。以下是RFC 4960-第6.4.1节-第二段

When there is outbound data to send and the primary path becomes
inactive (e.g., due to failures), or where the SCTP user explicitly
requests to send data to an inactive destination transport address,
before reporting an error to its ULP, the SCTP endpoint should try to
send the data to an alternate active destination transport address if
one exists.
