Amazon Direct Connect Failover Test

The Amazon Direct Connect Resiliency Toolkit resiliency models are designed to ensure that you have the appropriate number of virtual interface connections in multiple locations. After you complete the wizard, use the Amazon Direct Connect Resiliency Toolkit failover test to bring down the BGP peering session in order to verify that traffic routes to one of your redundant virtual interfaces, and meets your resiliency requirements.

Use the test to make sure that traffic routes over redundant virtual interfaces when a virtual interface is out of service. You start the test by selecting a virtual interface, BGP peering session, and how long to run the test. Amazon places the selected virtual interface BGP peering session in the down state. When the interface is in this state, traffic should go over a redundant virtual interface. If your configuration does not contain the appropriate redundant connections, the BGP peering session fails, and traffic does not get routed. When the test completes, or you manually stop the test, Amazon restores the BGP session. After the test is complete, you can use the Amazon Direct Connect Resiliency Toolkit to adjust your configuration.

Note

Do not use this feature during a Direct Connect maintenance period as the BGP session might be restored prematurely either during or after the maintenance.

Test History

Amazon deletes the test history after 365 days. The test history includes the status for tests that were run on all BGP peers. The history includes which BGP peering sessions were tested, the start and end times, and the test status, which can be any of the following values:

  • In progress - The test is currently running.

  • Completed - The test ran for the time that you specified.

  • Cancelled - The test was cancelled before the specified time.

  • Failed - The test did not run for the time that you specified. This can happen when there is an issue with the router.

Validation Permissions

The only account that has permission to run the failover test is the account that owns the virtual interface. The account owner receives an indication through Amazon CloudTrail that a test ran on a virtual interface.
