CentOS
I installed CentOS 6.5 and configured bond and bridge interface. Bond configuration file:
DEVICE=bond4.2301
NAME=bond4.2301
BONDING_MASTER=yes
IPV6INIT=no
VLAN=yes
ONBOOT=yes
BOOTPROTO=none
BRIDGE=br-ext
br-ex configuration file:
DEVICE=br-ext
BOOTPROTO=none
ONBOOT=yes
TYPE=OVSBridge
DEVICETYPE=ovs
USERCTL=no
PEERDNS=yes
IPV6INIT=no
STP=no
DELAY=5
My problem if I restart the computer the bridge can not start automatically on. I tried modify DELAY=0. But I write this command: service network start the bridge is start on. This is the log: kernel: br-ext: port 1(bond4.2301) entering forwarding state /etc/sysconfig/network-scripts/ifup-eth: Device br-ext does not seem to be present, delaying initialization. Can you help me wthat is the problem my configuration file? I checked /etc/udev/rules.d/70-persistent-net.rules. I configured two interface and 4 bonding and 4 bridge you can see the config top of the page.
