Scenario 3: vEdge Control Connection is DOWN and the vEdge HAS been rebooted. Scenario 2: vEdge Control Connection is DOWN and the vEdge HAS NOT been rebooted. Scenario 1: vEdge Control Connection is UP and the vEdge HAS NOT been rebooted.

The steps for remediation vary based on which scenario applies to each vEdge in your network.

Upgrade vEdge software to a fixed version.

Execute pre-checks to prepare to upgrade your vEdge software.

Restore control and BFD connections between vEdge and controllers.

Upgrade the SD-WAN controller(s) to a fixed version.

Execute pre-checks to prepare for the upgrade of your Controller(s).

The high-level process to remedy this problem is: Carefully read the entire process before you take any action. Remediation ProcessĬisco has published upgrade versions of software to permanently resolve this problem. Without a reload, the Data Plane (BFD) Sessions remain up and traffic is able to pass until the Graceful Restart timer is expired, even while control connections are down. In order to prevent a complete loss of service, AVOID these actions in this section.Ĭaution: Device reload causes the Graceful Restart Timers to reset and the router is not able to reconnect to the fabric.

Note: For more information about this behavior, reference Cisco bug ID CSCwf28118. When Enterprise Certificates are used, both the Onbox and Enterprise Certificates are validated. Note: During the Control Connection establishment, the Onbox certificate is validated by the controllers in all cases.
