Subject: [openstack-dev] [Neutron][Subnet] Unable to update external network subnet's gateway-ip

Hi All,

I am trying below scenario, please let me know the correctness of the scenario:-

1.       Create one external network i.e. with router:external=True option.

2.       Create one subnet under the above network with gateway-ip provided.

3.       Create one router.

4.       Issue command "neutron router-gateway-set <routerID-point3 above>  <networkID-point1 above>"

5.       Update the subnet in point2 above with new gateway IP i.e "neutron subnet-update <subnetID-point2>  --gateway-ip <newIP>"

6.       I can see success-full subnet updated response on cli.

7.       For validating the changed gateway-ip I verified router namespace present on Network node by using command "ip netns exec <router-namespace-point3> route -n". But in the output the new gateway-ip is not updated it is still showing the old one.

Brief about my setup:-

1.       It has one controller node, one Network node and 2 Compute nodes.

2.       I am on Icehouse-GA.


Regards,
Vishal
