  to my experience, unplumbing a virtual interface will remove the real interface too.
  so it would be wise to just bring it down instead of unplumbing.

  According to the <font color="orange">ifconfig man page</font>:
  
  
To delete a logical interface, simply name the interface
specifying an address of 0, after ensuring that the inter-
face has been marked as "down". For example, the command:

ifconfig le0:1 0 down
will delete the logical interface le0:1.

  
  
  The previous comment is correct that unplumbing a logical interface in Solaris will unplumb the physical interface, as plumbing is a "physical" matter.

  On Solaris 8, you can remove the virtual interface by using removeif option of the ifconfig command :
  
  ifconfig <physical_interface> removeif <logical_address>
  
  for eg.:
  
  $ ifconfig -a
  lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
  inet 127.0.0.1 netmask ff000000
  bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
  inet 1.2.31.216 netmask fffff800 broadcast 1.2.31.255
  bge0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
  inet 1.2.31.24 netmask fffff800 broadcast 1.2.31.255
  
  # ifconfig bge0 removeif 1.2.31.26
  
  $ ifconfig -a
  lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
  inet 127.0.0.1 netmask ff000000
  bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
  inet 1.2.31.216 netmask fffff800 broadcast 1.2.31.255
