Per http://jpetazzo.github.io/2013/10/16/co ... e-network/ I am trying to set up br0, as well as the private IP for the node.

/etc/network/interfaces:

iface eth0:0 inet static
  address 192.168.xxx.yyy
  netmask 255.255.128.0

auto br0
iface br0 inet static
  address 10.1.1.1
  netmask 255.255.255.0
  bridge_ports dummy0
  bridge_stp off
  bridge_fd 0

Neither`sudo /etc/init.d/networking restart` nor rebooting server shows either interface in `ifconfig` output.

Can you show your entire /etc/network/interfaces file?

Keep in mind that if you configure private networking on eth0:0, you should also configure eth0's primary IP address statically.

Keep in mind that on some distros (Ubuntu sticks out in my mind) the output of `ifconfig` just doesn't show aliases like eth0:0

It's always worked for me on Ubuntu Desktop and Server.
