Under what conditions are IPSEC P2 SA's built, broken down, and/or re-created?
I'm trying to root out the science under the phase 2 SA creation and mechanics so I can answer for myself what is the most efficient way to design our VPN tunnels. I always get subjective answers when I've asked before, so I'm coming at it different asking about HOW they work at a granular level. Thanks in advance.
