[rhos-list] How can I start br-ex interface across reboots

[Dave Neary]

Hi yimao,

I documented this in the "Networking" page on openstack.redhat.com.

In /etc/sysconfig/network-scripts/ifcfg-br-ex, put:

DEVICE=br-ex
TYPE=Ethernet
BOOTPROTO=static
ONBOOT=yes
IPADDR=<ip address>
NETMASK=255.255.255.0
GATEWAY=<gateway IP>
DNS1=<dns>
DNS2=<dns>
DOMAIN=<domain>
NAME="System br-ex"


I associated eth0 with br-ex, si I also had to remove the IP
configuration from the equivalent ifcfg-eth0 file. I have:
DEVICE=eth0
TYPE=Ethernet
UUID=88f7adf3-7bca-4076-8d06-98790a778f2e
ONBOOT=yes
NM_CONTROLLED=no
BOOTPROTO=static
NAME="System eth0"

Once I associated eth0 with br-ex, I was set.

Cheers,
Dave.
