I have discovered Brownfield VXLAN NX-OS switches into NDFC Version 12.1.3b and while doing "Recalculate and Deploy", I am getting error "Overlay VNI [2190001] in state [Down]" reported for all leaf switches. This VNI is associated with VLAN1 which is admin shut. Has anyone encountered this issue? What is the safest fix for it to move further with deploy?
