--------------------------------------------

             Summary: rVPC ACL doesn't recover after cleaning up through the NetworkGarbageCollector
                 Key: CLOUDSTACK-9189
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9189
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Virtual Router
    Affects Versions: 4.6.0, 4.7.0, 4.6.1, 4.6.2
            Reporter: Wilder Rodrigues
            Assignee: Wilder Rodrigues
            Priority: Critical
             Fix For: 4.7.1


In order to reproduce this bug quicker is better to change the network.gc.interval and gc.wait
from 600 seconds to 10 seconds via Global Settings and restart your management server.

- deploy a rVPC
- deploy VM in it
- make port forwarding (2nd ip, firewall and such)
- confirm it works
- stop the vm
- after some time (20 seconds * 3 - approximately) the network garbage collector will come
and tear down the network since there are no more VMs
- all the nics will be fine and the guest nic will be gone. The routers should be on BACKUP/BACKUP
- then start the vm again
- the nics get plugged again and keepalived will decide on a new master.
- try to SSH into the VM via the public IP. It will fail

The only way to get it working afain is:

- Replace the network ACL - for example, default allow all
- Try to SSH again and it works fine
- Replace back to your original ACL
- Try to SSH again and it works fine
