Overlay Transport Virtualization Commands
This chapter describes the Overlay Transport Virtualization (OTV) commands Cisco NX-OS for the Nexus 7000 Series devices.
authentication (OTV)
To configure an authentication keychain string for edge device authentication, use the authentication command. To return to the default setting, use the no form of this command.

Syntax Description
Defaults
None
Command Modes

Usage Guidelines
The authentication command is used to assign a password in the authentication of a hello protocol data unit. Only one authentication key chain is applied to an IS-IS interface at one time. If you configure a second authentication command, the first is overridden. You can specify authentication for an entire instance of IS-IS instead of at the interface level by using the authentication command.
This command requires a Transport Services license.
Examples
This example shows how to configure an authentication keychain string for edge device authentication:

Use the suppress-arp-nd OTV overlay interface command to suppress sending ARP and ND packets on overlay network. The ARP Requests and ND Neighbor Solicitations should be forwarded on the 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.
This command requires a Transport Services license.

Examples
This example shows how to suppress sending ARP and neighbor discovery ND packets on overlay network:
