Multiple instances within an NSsp can support stateful HA. This multi-instance HA model exactly mimics the NSv HA model in terms of the behavior and capabilities. Two instances can be paired to form a stateful HA. One of them resumes the role as a Primary active instance and the other as Secondary standby instance. The active and standby roles can change during an instance's lifetime.
This section explains how to form instance HA pairing within one NSsp.
