freebsd 10.0 not work carp protocol on Hyper-v

[Giovanni Mattera]

good morning 
I installed freebsd 10.0 on Hyper -V Windows Server 2012 R2. 
I would like to enable the CARP protocol but is still in a state of init . 
The error in dmessage is " ifa_del_loopback_route : deletion failed: 48" . 
How do you configure CARP on Hyper -V ? 
I've used both the card " Legacy Network " and " Network" but the result is the same. 
We are available to pay for this. 

Thank you.
