Usage guidelines
By default, the device learns ND information of remote VMs from packets received on VXLAN tunnel interfaces. To save resources on VTEPs in an SDN transport network, you can temporarily disable remote ND learning when the controller and VTEPs are synchronizing entries. After the entry synchronization is completed, use the undo vxlan tunnel nd-learning disable command to enable remote ND learning.
As a best practice, disable remote ND learning for VXLANs only when the controller and VTEPs are synchronizing entries.
