我遇到两个问题1、多个SP是否能与同一个ISAKMP-SA（phase 1）绑定？如果可以，这些SP有什么共同点？通常来说，绑定关系是 一个SP对一个ISAKMP 还是 多个SP对一个ISAKMP?2、使用同一个 phase 1 协商多个 phase 2 的条件是什么？

I currently have two questions1. Can multiple SPs be bound to the same ISAKMP-SA (phase 1)? If so, what do these SPs have in common? In general, is the binding relationship one-SP-to-one-ISAKMP or multiple-SPs-to-one-ISAKMP?2. What are the conditions...
