Can you be a bit more specific about your problem?
When you have install the bridge-utils package, which is required for
configuring bridges on Debian, you can put stanzas like this into the
/etc/network/interfaces file:
auto br123
iface br123 inet manual
bridge_ports eth42
bridge_stp no
bridge_fd 2
This will setup the bridge 'br123' and attach the physical NIC 'eth42'
to it, which practically means you have a virtual switch inside your
Dom0 where you can plug DomUs in. Dom0 will not be able to directly
communicate with them, though.
If you want your Dom0 to be part of this network, you have to
configure an IP address on the bridge which can be done like this:
auto br123
iface br123 inet static
addresss 10.0.123.42
netmask 255.255.255.0
bridge_ports eth42
bridge_stp no
bridge_fd 2
Beware of the 'static' vs. 'manual' thing.
If you are using VLANs you can go one step further an do something
like this (package vlan required)
auto eth0
iface eth0 inet manual
post-up ifconfig eth0 0.0.0.0 up
pre-down ifconfig eth0 0.0.0.0 down
auto eth0.123
iface eth0.123 inet manual
vlan_raw_device eth0
post-up ifconfig $IFACE 0.0.0.0 up
pre-down ifconfig $IFACE 0.0.0.0 down
auto br123
iface br123 inet static
addresss 10.0.123.42
netmask 255.255.255.0
bridge_ports eth0.123
bridge_stp no
bridge_fd 2
