Hello!
As Gaur said the SDA Desing uses Loopback 0 for fabric communication, more specifically I think this IP is used as the resolution IP that identifies your device for LIPS node controller. When you want to send a packet from one end point to another, the map resolution sever has to resolve which network device you need to reach first in order to reach the destination end point, an this server resolves this IP address as de VXLAN destination IP.
Please do not forgget to rate useful post.
