WIth DVR enabled, performing a 'neutron router-gateway-clear' creates a router namespace and a binding on every compute node.

Created a new router:

1) Create a router: neutron router-create test
2) Expect no router bindings with:
neutron l3-agent-list-hosting-router
3) Clear the gateway: neutron router-gateway-clear test
4) Expect no router bindings with:
neutron l3-agent-list-hosting-router
This time the command shows that the router is bound to an agent(s).
In the DVR case, this is particularly bad, as the binding may cause namespace creations on the hosts running the L3 agents. |
