I still think you're confusing Linux semantics with FreeBSD semantics.

On linux you would have:
eth0      Link encap:Ethernet  HWaddr 00:1E:C9:53:0B:61  
          inet addr:10.0.0.1  Bcast:10.0.0.255  Mask:255.255.255.0
          inet6 addr: fe80::21e:c9ff:fe53:b61/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:211328068 errors:0 dropped:0 overruns:0 frame:0
          TX packets:368394006 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:34065846811 (31.7 GiB)  TX bytes:476377525764 (443.6 GiB)
          Interrupt:169 Memory:e6000000-e6011100 

eth0:1    Link encap:Ethernet  HWaddr 00:1E:C9:53:0B:61  
          inet addr:10.0.1.1  Bcast:10.0.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          Interrupt:169 Memory:e6000000-e6011100 


On FreeBSD you would have:

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>
        ether 54:04:a6:96:0c:1e
        inet 10.0.0.1 netmask 0xffffff00 broadcast 10.0.0.255
        inet 10.0.1.1 netmask 0xffffff00 broadcast 10.0.1.255
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active

These are both the same thing.  Is there any particular reason that
you want multiple interfaces?  I can't see a use for it beyond "it's
what I'm used to seeing" unless they're VLAN interfaces.
