Scenario B: HA Pair in NAT/Route Mode
Scenario B: HA Pair in NAT/Route Mode
For network installations with two ADTRAN NetVanta 2730
appliances configured as a stateful synchronized pair for
redundant high availability networking.
In this scenario, one ADTRAN NetVanta 2730 operates as the
primary gateway device and the other ADTRAN NetVanta 2730
is in passive mode. All network connection information is
synchronized between the two devices so that the backup
appliance can seamlessly switch to active mode without
dropping any connections if the primary device loses
connectivity.
