[Linux-ha-dev] problem shutting down first created alias interfaces on linux

[Sebastian Reitenbach]

Hi,

I stumbled across a strange behavior of ifconfig/ip, regarding alias IP 
addresses on linux. I found this behaviour on suse 10.1, 10.2, 10.3 and 
SLES10SP1.

When you configure multiple aliases on an single interface, and you specify 
netmasks and broadcasts, and then try to shutdown just the first created 
alias then all IP aliases for that interface will be gone. Removing one of 
the later created aliases works as expected.

As I think virtual IP aliases are used often in HA environments, it might be 
of interest to you.
