Re: [Rdo-list] My router GWY is down and can not allocate floating IP

Hi Marius, Thank you for your help, but I believe now I have seriously wrong stuff but I am still not able to figure it out :-( 1. Check if you can reach the router's public IP --> I can reach the router public IP only from the network node, but not from any other node even in the same public subnet. 2. Check if you can reach the the default gateway from the router namespace: ip netns exec qrouter-2d9b71f1-6e54-4a05-a0fb-0680233d6dea ip a ip netns exec qrouter-2d9b71f1-6e54-4a05-a0fb-0680233d6dea ip r ip netns exec qrouter-2d9b71f1-6e54-4a05-a0fb-0680233d6dea ping 10.254.102.1 --> Here is the output of the commands: http://pastebin.com/SAPpUXUV 3. Do you want to enable dhcp on the public subnet? --> Yes I want so. Second, check the instance log if it received an IP address via dhcp and it was able to reach the metadata server. You should be able to see this via nova console-log or in Horizon. --> I do not have console.log, I have only these files: nova-api.log nova-cert.log nova-compute.log nova-conductor.log nova-consoleauth.log nova-manage.log nova-novncproxy.log nova-scheduler.log But I attach you a photo from the Horizon Since you are using vlan networks you should check that the /etc/neutron/plugins/ml2/openvswitch_agent.ini contains the correct bridge_mappings - physnet1 is mapped to the bridge that contains the physical nic where vlans 10,15 are passed through. --> I do not have this file, here the list of files in the plugins directory: http://pastebin.com/EMTzehnh Also check that external_network_bridge is set to an empty value in /etc/neutron/l3_agent.ini --> Here is the content of the file, I do not anything wrong: http://pastebin.com/nAiEnaTs Here is a guide on how to deploy Neutron with an existing external network, hope it helps: https://www.rdoproject.org/networking/neutron-with-existing-external-netw... --> I believe there is something wrong in the installation, but I can not figure out what I did wrong that I am missing the file /etc/neutron/plugins/ml2/openvswitch_agent.ini!!! -----Original Message----- From: Marius Cornea [mailto:marius@remote-lab.net] Sent: Tuesday, 16 February 2016 8:18 PM To: Ashraf Hassan <asma2103(a)yahoo.com&gt; Cc: rdo-list <rdo-list(a)redhat.com&gt; Subject: Re: [Rdo-list] My router GWY is down and can not allocate floating IP Hi, There are a couple of things that you can check: First, let's see if the public facing connectivity to the router is working properly: 1. Check if you can reach the router's public IP 2. Check if you can reach the the default gateway from the router namespace: ip netns exec qrouter-2d9b71f1-6e54-4a05-a0fb-0680233d6dea ip a ip netns exec qrouter-2d9b71f1-6e54-4a05-a0fb-0680233d6dea ip r ip netns exec qrouter-2d9b71f1-6e54-4a05-a0fb-0680233d6dea ping 10.254.102.1 3.
