Configuring Cisco ASA Active-Standby Failover using ASDM
In this post I will be configuring active –standby failover with Cisco ASA.I will using the wizard driven configuration which allows to understand each and every aspect of the configuration and it makes it easy to troubleshoot.
Prerequisites for Active/Standby Failover
Active/Standby failover has the following prerequisites:
•Both units must be identical ASAs that are connected to each other through a dedicated failover link and, optionally, a Stateful Failover link.
•Both units must have the same software configuration and the proper license.
•Both units must be in the same mode (single or multiple, transparent or routed).
I will be using the following simple topology to test my failover setup.
