------------------------------------------
Hugo:
On the host 10.223.58.195 , After I changed
/etc/sysconfig/network-scripts/ifcfg-eth1 and
/etc/sysconfig/network-scripts/ifcfg-cloudbr to your instructions, service
network restart ,
the host can ONLY ping its own gateway 10.223.58.193 and any host in same
subnet,
but CANNOT reach anything beyond the gateway 10.223.58.193.
1. /etc/sysconfig/network-scripts/ifcfg-eth1:
DEVICE=eth1
BOOTPROTO=none
HWADDR=BC:30:5B:D4:16:3C
IPV6INIT=no
#MTU=1500
NM_CONTROLLED=no
ONBOOT=yes
#TYPE=Ethernet
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=cloudbr
#UUID="0142ba15-de11-499c-a1ba-82837b30f890"
#IPADDR=10.223.58.195
#NETMASK=255.255.255.192
#GATEWAY=10.223.58.193
#DNS1=10.223.110.254
#USERCTL=yes
#IPV4_FAILURE_FATAL=yes
#DEFROUTE=yes
#NAME="System eth1"
2. /etc/sysconfig/network-scripts/ifcfg-cloudbr:
DEVICE=cloudbr
ONBOOT=yes
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=10.223.58.195
GATEWAY=10.23.58.193
NETMASK=255.255.255.0
HOTPLUG=no
3. On host 10.223.58.195, service network restart
4. on host 10.223.58.195:
[root@Rack3Host16 ~]# ip route
10.223.58.0/24 dev cloudbr proto kernel scope link src 10.223.58.195
169.254.0.0/16 dev cloud0 proto kernel scope link src 169.254.0.1
169.254.0.0/16 dev eth1 scope link metric 1002
169.254.0.0/16 dev cloudbr scope link metric 1015
5. It can reach its gateway & other hosts on same gateway:
