VXLAN Part X: Recovery issue when BGP EVPN peering uses the same loopback interface as a source than VXLAN NVE1 interface

Now you can also download my VXLAN book from the Leanpub.com 

"Virtual Extensible LAN VXLAN - A Practical guide to VXLAN Solution Part 1. (373 pages)

Does it really matter if the NVE1 interface of a VTEP switch and BGP EVPN use the same Loopback interface IP address as a source or should there be a dedicated Loopback interface for BGP EVPN? In this post, I am trying to give an answer by showing the difference in BGP EVPN convergence process for both of these design options.
