Overlay Transport Virtualization Commands
This chapter describes the Cisco NX-OS Overlay Transport Virtualization (OTV) commands for the Nexus 7000 Series devices.
authentication (OTV)

The ARP Requests and ND Neighbor Solicitations should be forwarded on an overlay network when the OTV edge device has state for the IPv4 or IPv6 target address. When you use this command, the number of broadcasts/multicast packets sent on the overlay is drastically reduced.
Note IPv6 is not supported in this release.
Examples
This example shows how to suppress sending ARP and ND packets on an overlay network:
