A bridge slave needs an ifindex, and alias interfaces don't have their own separate device/ifindex. Thus, you are anyway enslaving the whole eth0.So the next question. Can I have a bridge with eth0 *and* an eth0:0 alias and expect things to work?
Interface aliases are concerned with the IP configuration (Layer 3) of the device. Once you enslave the device eth0 to a bridge, it has no more layer 3 properties and thus it makes no sense to have IP configuration there. Enslave eth0 and configure your IP addresses on the bridge device itself, like having a "br0:0" ... Thomas
