Now the bridge transports packets, but the setup is a little bit weird:
first:
All interfaces are configured (in Debian-Woody) in /etc/network/interfaces
like this one: (the used IP-address is only a dummy-address needed for
hardware-initialisation)
This means - for all non-Debian-using people: all these interfaces are
initialized
at boottime with the given parameters.
auto eth<n>
iface eth<n> inet static
address 10.11.12.1
netmask 255.255.255.0
broadcast 10.11.12.255
network 10.11.12.0
second:
create the bridge and add the interfaces:
brctl addbr br0
brctl addif br0 eth1
brctl addif br0 eth2
brctl addif br0 eth<n>
...
third:
start the bridge:
ip link set br0 up
Bridge is working.....
Explanations:
Debian-Woody: The "ip"-command is in the package "iproute".
---------
I do not understand exact, why this is needed, but here is my theory:
The tulip-chip has no internal MII-Transceiver. These chips are external
and needs to become initialized separatly. This is done with the tulip-driver
after initializing the interface on normal startup. Only loading the tulip-module
is not sufficient for that initialisation.
So, starting the interface with an IP-address first initializes the Transceiver
correctly, and adding later the interfaces to the bridge, does not destroy the
initialisation of the transceivers.
Starting the bridge with the command "ifconfig br0 up" noes not work, but I do not
know why.
----------
If someone has deeper knowledge of this phenomena, please explain it to us.
Thank you
