Remi Bergsma commented on CLOUDSTACK-9154:
------------------------------------------
Stopping the vm, destroying both routers, then starting the vm resolves it.
```

```
At least we have a work-around.
> rVPC doesn't recover from cleaning up of network scavenger

> 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
> Environment: ACS 4.7
> Reporter: Remi Bergsma
>
> - 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 scavenger 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:
