Are you not sure what it should do once real machines are gone and a
network is still present?
The tests do:
1. Deploy a DC
2. Create a VPC + Tier + VM
3. Change the GC settings for 10 seconds, for example
4. Restart the Management Server
5. Remove the VM from the tier
After that, the tests sleeps the time needed (based on GC interval/wait) in
order to check if the routers are in the correct state once the guest networks
are gone.
I will run the tests with the changes to see how it goes.
Cheers,
Wilder

> Key: CLOUDSTACK-9154
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9154
> 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
> Environment: ACS 4.7
> Reporter: Remi Bergsma
> Assignee: Wilder Rodrigues
> Priority: Critical
> Fix For: 4.7.1
>
>
> - deploy a rVPC
> - deploy VM in it
> - make port forwarding (2nd ip, firewall and such)
> - confirm it works
> - stop the vm
> - after some time the network garbage collector will come and tear down the
> network since there are no more VMs
> - keepalived will enter FAULT state because of missing eth2 nic (which was
> first network tier)
> - all is left is ethic (link local) and lo0
> - then start the vm again
> - the nics get plugged again and keepalived will decide on a new master
> - the nics are screwed up after this:
