Howto create an empty bridge?

[COiN3D]

Hi there,

by using "brctl add bridgename" it is possible, to create an empty bridge without any interfaces in it. I guess that gentoo doesnt allow that. When I add

Code: Select all

bridge_xenbr0=""

config_xenbr0=( "10.0.0.1/24" )

in /etc/conf.d/net, it gives me errors starting my bridge:

Code: Select all

 # /etc/init.d/net.xenbr0 start
 * Starting xenbr0
 *   Bringing up xenbr0
 *     10.0.0.1/24
 *     network interface xenbr0 does not exist
 *     Please verify hardware or kernel module (driver)
                                                                          [ !! ]
                                                                          [ !! ]

Only if I create the empty bridge with brctl add xenbr0, gentoos init script is able to give it an network address. Is there a work around for that?

Thanks

I didn't really solve the problem but created an evil work-around by creating a "dummy" tuntap device.

Code: Select all

tuntap_dummy="tap"
config_dummy=( "null" )

#config_eth0=( "null" )

bridge_xenbr0="dummy"
config_xenbr0=( "10.0.0.1/24" )
