22.4. Recovering a Lost Virtual Router

Symptom
A virtual router is running, but the host is disconnected. A virtual router no longer functions as expected.
Cause
The Virtual router is lost or down.
Solution
If you are sure that a virtual router is down forever, or no longer functions as expected, destroy it. You must create one afresh while keeping the backup router up and running (it is assumed this is in a redundant router setup):
Recreate the missing router by using the restartNetwork API with cleanup=false parameter. For more information about redundant router setup, see Creating a New Network Offering.
For more information about the API syntax, see the API Reference at http://docs.cloudstack.org/CloudStack_Documentation/API_Reference%3A_CloudStackAPI Reference.
