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

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.

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.
