could not complete action .

InternalError:=> Device doesn't have loopback 0 interface or there is 
no ip adress configured on loopback 0 interface

why i need Loopback 0 interface ??

[Gaur Samal]

As per SDA design, it uses Loopback 0 for all fabric communication for the device. Hence, before you provision/assign fabric role to any device, you need to configure L0.

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.
