Please refer to the summary at: https://mailarchive.ietf.org/arch/msg/lisp/mWukquyGiXnsMwxxvCwhTY2K1HM/. We are following that conclusion. > ### Section 5 and intended status > > ``` > The exact details to characterize such policies are deployment and > implementation specific.

Like with any rate limit recommendation, I don't think we can mandate by design a specific way to enforce it or how a server can control the number of state it maintains. > An experimental status would be more comforting. > > ### Missed notification > > If for any reason a Map-Notify is missed (e.g., publisher is > overloaded), then > what is the fall-back ?
