Description (partial)

A 1 minute (60 second) negative-map-reply (NMR) causes a race condition, preventing the border node from populating its map-cache, and from allowing external communication to reach the endpoints in the fabric.

This was observed in an installation where the border node and the control plane node are on separate devices.  The endpoint ID (EID) has not been registered, though a source outside of the fabric site is attempting to communicate with that endpoint.
