Sorry No No. that is the ip address of the virtual router. You need to ping the gateway using the router. So it should look like this

ip netns exec qrouter-48cc6f75-b0a2-4468-a0bd-e6567237b7ee ping -I  qg-34625a11-da 172.29.105.1

Hi Remo,

Thank you for looking at this issue. Yes, I can ping the gateway from the router. Please look the red in the following my previous mail.  I followed the OpenStack installation guide, http://docs.openstack.org/icehouse/install-guide/install/apt/content/neutron_initial-tenant-network.html, to set up the network. More detail networks and router are in the following: Please let me know if you need any more information.

Thanks,

that only shows you ping your interface can you ping your gateway from the router? How was the router created? Did you enable provider network? You show some data but not all.

These is an issue that the tenant router gateway can not be pinned. Is this an OpenStack issue? It doesnâ??t allow all nodes to be powered off and on? Before the nodes were shut down, networking works great either from inside instances to access outside internet or from outside to access the instances. Please help:

I also restarted the neutron services after my neutron node booted up.
service neutron-plugin-openvswitch-agent restart
service neutron-l3-agent restart
service neutron-dhcp-agent restart

Anyone has solutions for this kind of issue?


Thank you so much for the help,

Hi All,

I followed the OpenStack icehouse installation guide to successfully install a five node system, one control node, one neutron and three compute nodes.  Inside of the instance, I can ping other instancesâ?? virtual IP address and outside internet fine. Recently, we decided to move all the nodes to a lab. So, I powered down the five nodes before the move and powered up them afterward. All the physical network connections were exactly the same as they were before the move. But, I can not even ping other instance after the five nodes up again.

I typed â??route â??nâ?? inside of the instance, no any IP is shown. Whatâ??s wrong? Please help how I can get the instance networking back.

Thanks,
