Thanks, I did this step . So what is next ? Sorry to bother but you are really a life saver to me (thanks to you a ton) as well kashyap .

I have deleted all network (admin) and tenant as I wanted your guidance to do further
Can you help to give steps to add the network again (10.48.146.0/24<http://10.48.146.0/24>) and tenant 192.168.10.0/24<http://192.168.10.0/24> after floating ip to 10.48.146.113)

Let's keep the troubleshooting steps on the list. What's the output of 'nova list' ?

Yes, I did boot the instance but its getting 10.48.146.4 address rather 192.168.*** that you gave me ? I can logon to the instance console 10.48.146.4 and can ping gateway 10.48.146.1 but I cannot ssh or ping from host?
Is it possible I share my screen, so that you can guide me what wrong thing that stops and bother me ?

You've already defined router1 which is already connected to the external network. You can use that. ext-net is the 'public' network in your case.

Ok I did the folowing steps for tenant.
1) neutron net-create demo-net
2) neutron subnet-create demo-net --name demo-subnet --gateway 10.48.146.1 10.48.146.0/24<http://10.48.146.0/24>
3) neutron router-create demo-router
4) neutron router-interface-add demo-router demo-subnet
Anything left .?

Hi Marius,
Yes, I can ping 10.48.146.113 (gateway) from the host , can you provide the comamnds or link to create tenant network, subjet and attach to router ?

Can you ping 10.48.146.113 from your network? You also need to create a tenant network, subnet and attach it to the router. Boot the instance with the tenant network attached and then assign it the floating IP.

Hi Marius,
I did this first and now can see the BR-ex is the same IP as my eno1 interface , you are right I lost first while doing the first command(ip addr del 10.48.146.77/24<http://10.48.146.77/24> dev eno1) and then conneting to console I did the second comand (ovs-vsctl add-port br-ex eno1 and also changed the IP address of br-ex to 10.48.146.77)
ip addr del 10.48.146.77/24<http://10.48.146.77/24> dev eno1; ovs-vsctl add-port br-ex eno1
Then after I removed all the routers, networks and interfaces from openstack and ran the following 4 commands.
1) source /root/keystonerc_admin
2) neutron net-create public --router:external=True
3) neutron subnet-create public 10.48.146.0/24<http://10.48.146.0/24> --name vlan --enable_dhcp=False --allocation_pool start=10.48.146.113,end=10.48.146.130 --gateway 10.48.146.1
4) neutron router-create router1
5) neutron router-gateway-set 7e07fef0-e92b-4956-9b23-82157d81ebf3 1605ac0b-4f59-473d-b20f-911c3401dc2c
6) neutron floatingip-create public
The above command generated a floating IP 10.48.146.115
Then I spin up a new instance and it got IP assigned automatically 10.48.146.115, howevr I cannot ping or ssh to that ip : 10.48.146.115 ?

As Kashyap kindly suggested we're not a support line and information here should be available for all the community members. First, I don't see how you can ping the br-ex IP address from an external network since it doesn't contain any physical interface. Make sure that 10.48.146.112 isn't used by other host on you network segment. You can do the following to remove the ip address from the physical interface and add it to the br-ex bridge. Please make sure that you've got console access to the server before doing this as you may lose connectivity.
# ip addr del 10.48.146.77/24<http://10.48.146.77/24> dev eno1; ovs-vsctl add-port br-ex eno1
You should then follow the documentation[1] to recreate the public/tenant networks and router. In your case FLOATING_IP_START, FLOATING_IP_END should be part of the 10.48.146.0/24<http://10.48.146.0/24> network. Let's say you wish to allocate IP addresses of the 10.48.146.200 - 10.48.146.210 range to your Openstack routers/instances, then FLOATING_IP_START=10.48.146.200 and FLOATING_IP_END=10.48.146.210. EXTERNAL_NETWORK_GATEWAY should be set to what 'ip r | grep default | awk {'print $3'}' outputs and EXTERNAL_NETWORK_CIDR is 10.48.146.0/24<http://10.48.146.0/24>.
Note that the instance will get an IP address of the tenant network. By assigning a floating IP you will be able to access it through an IP address from your physical network segment.

Hi Rushi,
Can you provide the output of the following commands on your node ?
# ip a
# ovs-vsctl show
# neutron net-list
# neutron subnet-list
# neutron router-list
Please note that only the br-ex bridge requires an IP address, the interface that's part of it shouldn't have one assigned. Also the floating IP addresses will be used for DNAT on the tenant router. You can check the documentation here[1] that describes the use of floating IPs.
You can also check the upstream documentation[2] on how to create the networks.
[1] https://openstack.redhat.com/Difference_between_Floating_IP_and_private_IP
[2] http://docs.openstack.org/juno/install-guide/install/yum/content/neutron_initial-external-network.html
Tnx,
Marius

Hi Support,
I have a problem that a launched instance from openstack cannot connect to SSH or PING
First of all I have dump question whether my system should be NOVA network or Neutron network. Well to keep everyone on the same page. Here is my history.
1. I did install RDO (allinone host) using the bellow steps https://openstack.redhat.com/Quickstart
2. Then I have used the following steps for floating IP https://openstack.redhat.com/Floating_IP_range.
My situtation is as follows.
* Floating IP address assignment:
I have assigned a floating IP , I did follow this steps.
https://openstack.redhat.com/Floating_IP_range
* Bridge configuration:My Ethernet device eth0(actually in Redhat 7 it is eno1 name)is on the same bridge as the compute host
Yes, ethernet device on 10.48.146.78 address and br-ex interface on 10.48.146.112
* DHCP configuration: Yes, DHCP configuration is set and Neutron hearing and responding to DHCP
requests and the instance is getting IP from 10.48.146.113 (next hop) however I cannot ping/ssh to that IP address (ICMP/SSH is added allowed
rule on default security group)
Here is the little diagram of my system.
[cid:EB813931-0B05-459C-A0B6-DE7C98D3D2FA]
Can someone help to find what is missing.
Best Regards,
Rushi.
