Re: CPU Utiliaztion on a ethernet bridge

Hi!

I don't think that I could address your problem, but in Debian there is a
package called bridge-utils that allows easy bridge creation.

One of my systems uses it for a user-mode-linux installation between tap0
and eth2:

-------------
auto tap0
iface tap0 inet manual
        tunctl_user uml-net

auto eth2
iface eth2 inet manual

auto br0
iface br0 inet manual
        bridge_ports eth2 tap0
        bridge_stp on
------------

As you can notice  in my example, the iface method shouldn't be loopback
(it isn't the lo device). Try using the "manual" method if it helps


Regards
