"dhclient br0" should work. This is the same behavior as the Linux bridge, so if you've used that, then this works the same way. rhel/README.RHEL in the source distribution has some information on Red Hat network script integration. It was contributed; I haven't personally tried it. On Thu, Jan

Thanks. But the IP is coming from DHCP. How do I enable DHCP on the bridge? And how do I prevent eth0 from getting that IP address? I am assuming I dont have to go muck with ifcfg-eth0 under /etc/sysconfig/network-scripts nor do I have to create ifcfg-br0 in the same place. Tyrion On Thu, Jan 5
