Dual home FEX with Nexus 9396PX and support for MP-BGP on the same switch?

Hello all.

We just bought ourselves 4 Nexus 9396 switches for 2 of our datacenters. 

When sitting and playing around with them im trying to get a FEX to be multihomed towards 2 of the Nexus 9k switches but it seems to be abit of a struggle. 

It will connect fine to the first 9k switch but not with the other.

When configuring the first 9k switch it detects the fex and the fex is associated fine. When the secondary 9k is configured in this manner the fex is listed as offline for some reason. 

Also i can not configure the the portchannel that it is connected to as VPC (which probably explains why i the fex is marked as offline on the second 9k) it just says "ERROR: Operation failed: [FEX interface is not capable of acting as vPC]" as i understand it this is means a no go on multihomeing FEXes? 

 

Also i am playing around with BGP on the switch. When im trying to configure MP-BGP the VPNV4 addressfamily is nnowhere to be found?

aka-dc-core01(config-router)# router bgp 65001
aka-dc-core01(config-router)# address-family ?
  ipv4  Configure IPv4 address-family
  ipv6  Configure IPv6 address-family

When trying to activate under neighbour the same result 

aka-dc-core01(config-router)# neighbor 10.0.0.1 remote-as 65001
aka-dc-core01(config-router-neighbor)# address-family ?
  ipv4  Configure IPv4 address-family
  ipv6  Configure IPv6 address-family

 

We are running  NXOS: version 6.1(2)I2(3)

As we are waiting on the smartnet to go through i thought i would check if others are having the same issues?
