>Description:
We installed freebsd 10.0 on Hyper-V Windows Server 2012 R2.
We 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".
I've used both the adapter "Legacy Network" and "Network" but the result is the same.
