我正在嘗試為 openstack(packstack) 建立一個 ovs 橋接網路。我遇到了一個問題，根據文檔我需要建立如下所示的介面。
/etc/sysconfig/network-scripts/ifcfg-br-ex
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=192.168.122.212 # Old eth0 IP since we want the network restart to not
# kill the connection, otherwise pick something outside your dhcp range
NETMASK=255.255.255.0 # your netmask
GATEWAY=192.168.122.1 # your gateway
DNS1=192.168.122.1 # your nameserver
ONBOOT=yes
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex
ONBOOT=yes
hetzner中現有的配置如下：
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
HWADDR=hardware address
BOOTPROTO=none
IPADDR=<public ip>
NETMASK=255.255.255.255
SCOPE="peer <gateway ip>"
IPV6INIT=yes
IPV6ADDR=<ipv6 address>/64
IPV6_DEFAULTGW=fe80::1
IPV6_DEFAULTDEV=eth0
/etc/sysconfig/網路腳本/router-eth0
### Hetzner Online GmbH - installimage
# routing for eth0
ADDRESS0=0.0.0.0
NETMASK0=0.0.0.0
GATEWAY0=<gateway ip>
如何在hetzner伺服器中配置br-ex（OVS網橋），其中route-eth0中提到eth0（ipv6）介面網關？
