For my bridge use, I have actually altered the
ifcfg-br0 script itself. It is actually sourced
during the up/down, so you can add code. After all
your variable definitions add something like this:
if [ "$0" = "/sbin/ifup" -o "$0" = "./ifup" ] ; then
ip link set eth0 up
ip link set eth1 up
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
if [ "$0" =
"/etc/sysconfig/network-scripts/ifdown-post" ] ; then
brctl delbr br0
ip link set eth0 down
ip link set eth1 down
NOTE: '$0' has changed a bit over revisions, I have
found. If the up or down do not work, use an echo $0
to see what the script name is.
