Citrix SD-WAN Platforms
Note
The AWS design has a limitation of instances dependent on the AWS servers to respond for attach
and detach. The fail-over time is unpredictable.
Configuration steps
1. Acquire information about your high availability Peer Instance about information on the num-
ber of ENIs associated and details of ENIs associated using the REST API.
2. Detect the condition of the failing instance.
3. Call Detach of ENIs from failing instance using REST APIs.
4. Ensure all ENIs associated are detached.
5. Attach ENIs to the current Primary instance.
6. Ensure All ENIs are attached.
7. Trigger upper layers to detect that new ENIs are in place.
