I've got a network interface with 3 IP addresses. I can't delete the
third alias. Is it possible to delete this alias without taking hte
interface down?
cabernet# ifconfig fxp0
fxp0: flags=3D9843<UP,BROADCAST,RUNNING,SIMPLEX,LINK0,MULTICAST> mtu 1500

cabernet# ifconfig fxp0 -alias 209.223.7.161
ifconfig: ioctl (SIOCDIFADDR): Can't assign requested address
OK, maybe there's some other reference in the system that I need to
delete like a route or an arp entry.
