Dear Stackers,
Is possible to create public network without floating ip,
I have lan network: 192.168.100.0/24
i want my instance have 2 eth
eth0 (private network): 10.8.8.0/24
eth1 (public ip that connect to my lan network): 192.168.100.0/24
I use neutron flat network and gre
Thank you
Dear Ranjit,
Thank you so much for your help, really appreciate that.
I already solve the issue, so must add ovs bridge at network node and compute node. I just add it on network node only, now everything is working...
Thank you so much
Dear Ranjit,
This is the network node configuration
ovs-vsctl show
root@network1:/etc/init.d# ovs-vsctl show

Have you tried the provider flat network options while creating network. I think using that it's possible
Dear Ranjit,
Yes i tried, but flat network only can be used for floating ip, when i used flat network directly instance failed to create
Some time back, i had followed this link https://developer.rackspace.com/blog/... to setup flat network and able to assign ip on VM's eth0 from LAN network(in your case 192.168.100.0/24) . Try it.
Dear Ranjit,
I try follow the given link, but still not working. I can't build an instance and the network::dhcp ip can't be ping from my lan. Btw i use ml2 plugin
Have any idea??
Thank you
iqbal, Need below info.
