Public bug reported:
With the current implement, under certain curcumstance, router
information(including internal-stored data, iptables settings) kept and
set up by metering-agent could be inconsistent with what the neutron-
server suppose it to be. And that cause the metering-agent to run into a
problematic status.
Version:
Neutron master commit 7327e8c21(Merge "Fix update target tenant RBAC external
path")
Steps to reproduce:
1. Create internal net, subnet, router. Set external gateway for router, add
interface to the router for the created subnet.
2. Create neutron metering label and rule.
3. Make sure the created router is added to an active l3-agent.
4. Create another router and set its external gateway.
5. Use 'neutron l3-agent-router-remove' to remove the first router from the l3
agent.
6. Use 'neutron l3-agent-router-add' to add the first router back to the l3
agent by which it was hosted.
(In the following logs, the first created router's id is
0dd35572-735a-4ecd-8429-e047ed385100, the second one is
392820a7-3908-49eb-98a3-967f1638432f)

Title:
Metering-agent's routers information is inconsistent with neutron-
server
Status in neutron:
In Progress
Bug description:
With the current implement, under certain curcumstance, router
information(including internal-stored data, iptables settings) kept
and set up by metering-agent could be inconsistent with what the
neutron-server suppose it to be. And that cause the metering-agent to
run into a problematic status.
Version:
Neutron master commit 7327e8c21(Merge "Fix update target tenant RBAC external
path")
Steps to reproduce:
1. Create internal net, subnet, router. Set external gateway for router, add
interface to the router for the created subnet.
2. Create neutron metering label and rule.
3. Make sure the created router is added to an active l3-agent.
4. Create another router and set its external gateway.
5. Use 'neutron l3-agent-router-remove' to remove the first router from the
l3 agent.
6. Use 'neutron l3-agent-router-add' to add the first router back to the l3
agent by which it was hosted.
(In the following logs, the first created router's id is
0dd35572-735a-4ecd-8429-e047ed385100, the second one is
