openvswitch


hi,
i have centos 7 with openvswitch:
ens33: <BROADCAST,MULTICAST,UP,LOWER_UP>
ens37: <BROADCAST,MULTICAST,UP,LOWER_UP>
ovs-br0: <BROADCAST,UP,LOWER_UP>
ovs-br1: <BROADCAST,UP,LOWER_UP>


where
more ifcfg-ens33
DEVICE=ens33
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=ovs-br0
ONBOOT=yes
more ifcfg-ovs-br0
DEVICE=ovs-br0
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=192.168.42.99
NETMASK=255.255.255.0
GATEWAY=192.168.42.2
ONBOOT=yes

why after reboot ovs-br0 and ovs-br1 not have IP on them.
only after systemctl restart network the IP will be on those interfaces.

ens33: <BROADCAST,MULTICAST,UP,LOWER_UP>
ens37: <BROADCAST,MULTICAST,UP,LOWER_UP>
ovs-br0: <BROADCAST,UP,LOWER_UP>
inet 192.168.42.99/24 brd 192.168.42.255
ovs-br1: <BROADCAST,UP,LOWER_UP>
inet 192.168.42.100/24 brd 192.168.42.255

why i can ssh from my laptop only on IP on ovs-br0?
i have vmware -inside is centos 7.
tnx

If in bridge mode or switch mode, IP address is for management only. One switch just need one IP address.
