Correct is C https://www.cisco.com/c/dam/en/us/products/collateral/switches/nexus-7000-series-switches/guide_c07-728315.pdf With the Cisco NX-OS Release 6.2(2), we now support selective unknown unicast flooding based on the MAC address. In order to use this feature, the following one-line configuration must be added: OTV-VDC(config)# otv flood mac 0000.2101.1111 vlan 72

Shouldn't this be C? otv flood mac To enable selective unicast Overlay Transport Virtualization (OTV) flooding, use the otv flood mac command. To revert to the default setting, use the no form of this command. otv flood mac mac-address vlan vlan-id
