Because that requires re-arping of the IP address in the failover case. Also, I'm not sure whether I want to restrict the HA configuration to IP only. Supporting AppleTalk failover would also be useful. > If you do it at the ethernet level then the backup server can't be used for > other things as its's ethernet adress will disapear if you change the ethernet > adress on it. For a good HA configuration, multiple ethernet interfaces are useful anyway. Also, many ethernet chips support multiple ethernet addresses on a single ethernet interface.
