  Hi,

I wrote a script which generically set a bridge on some machines running=20
OpenSuse. Basically the script copy a bridge configuration file in=20
/etc/sysconfig/network (ifcfg-br0) and delete the eth0 (ifcfg-eth0)=20
config file. After a reboot the computer have an interface br0, a bridge=20
which is accessing the network through eth0.

I'm using IPv6 which calculate the address thanks to the MAC address. At=20
first, right after the machine boot, the address is clearly based on the=20
eth0 MAC address. My problem is that then, it get calculated from the=20
bridge MAC address which is, I believe, pretty random.

How can I fix that ? By declaring a static MAC address to the bridge ?=20
Is that possible / a good way to fix my problem ?

Thanks for your time and answers,
Regards,
