Router gateway to public network status is down
I have installed icehouse openstack installation on Ubuntu 14.04 with three nodes, controller,compute and network node. After creating of router through neutron API with two interface , I am not able to ping any of ther router interface, even through internal interface shows up. When checked in Horizon, I found that the router's internal interface status is ACTIVE and Admin Status is UP. Router's external interface/gateway status is DOWN and Admin Status is UP. I have tried to check whether gateway of router is properly set using command net-gateway-list command, but getting error 404 resource not found. I have also given a ovs-vsctl command on network node which shows following output.
sudo ovs-vsctl list-br br-ex br-int br-tun
master@openNetwork:~$ sudo ovs-vsctl list-ports br-ex eth2 eth6 qg-b464de3a-a1
master@openNetwork:~$ sudo ovs-vsctl list-ports br-int eth1 patch-tun qr-32945e19-2f
master@openNetwork:~$ sudo ovs-vsctl list-ports br-tun gre-0a00000e patch-int
sudo ovs-vsctl list-ports br-ex shows interface eth2 which i have not used any where and neither it is enabled by me.

That is normal
I think that's a red herring. I have a very similar setup. My external interface always shows a down status and
net-gateway-listreturns a 404, however, everything is working great. I think you problem lies elsewhere.But, then why I am not able to access any of the interface of my openstack router.
Kindly find the below output on controller node neutron router-list +--------------------------------------+------------+-----------------------------------------------------------------------------+ | id | name | external_gateway_info | +--------------------------------------+------------+-----------------------------------------------------------------------------+ | a703e133-ae5a-476b-aa0f-d6dbbd8b000a | ent-router | {"network_id": "e3f058b2-d2bb-43c7-945f-36af4f64b932", "enable_snat": true} | +--------------------------------------+------------+-----------------------------------------------------------------------------+ master@openController:~$ neutron port-list +--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+ | id | name | mac_address | fixed_ips | +--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+ | 32945e19-2f64-4f7a-a7f2-7e419ad9dd54 | | fa:16:3e:17:c1:42 | {"subnet_id": "1adcd921-1ff1-40cb-98db-aa43faee6bdb", "ip_address": "192.168.1.100"} | | b464de3a-a139-436a-b3cf-999f865f53c0 | | fa:16:3e:77:bf:4f | {"subnet_id": "0f1a0c87-691c-4169-a8c8-157bc3261393", "ip_address": "172.30.6.17"} | +--------------------------------------+------+-------------------+--------------------------------------------------------------------------------------+ I am not able to access either of the above addresses.
