N7K OTV Unicast mode

We are setting up OTV on the N7K in unicast mode.  Do I still need IGMP v3 configured on the join interface ?  And then on the Other side of the Join interface does that interface need IGMP v3 enabled as well? 

example

Production VDC:

interface port-channel8

  description to OTV-VDC-Join Interface

  mtu 1600

  ip address 172.23.1.213/30

  ip ospf network point-to-point

  ip router ospf 2 area 0.0.0.0

  ip igmp version 3

OTV VDC:

interface port-channel8

  description to Production-VDC _Join Interface

  mtu 1600

  ip address 172.23.1.214/30

  ip router ospf 2 area 0.0.0.0

ip igmp version 3

interface Overlay0

  otv join-interface port-channel8

  otv extend-vlan 201

  otv adjacency-server unicast-only

  no shutdown

Have a look at this guide that provides a configuration example for Unicast mode

http://www.cisco.com/en/US/docs/solutions/Enterprise/Data_Center/DCI/whitepaper/DCI_A.html

See below a snippet from the guide

interface Ethernet2/5

  description [ To the OTV Join-Interface ]

  ip address 172.26.255.97/30

  ip ospf network point-to-point

  ip router ospf 2 area 0.0.0.0

  ip pim sparse-mode

  ip igmp version 3

  no shutdown

You still need a command "ip igmp ver 3", the only difference in the configuration point of view is in the Overlay Interface.
