Overview of active-active FWLB

Active-active operation provides redundancy in case a ServerIron ADX becomes unavailable, while

enhancing performance by using both ServerIron ADXs to process and forward traffic.

NOTE

Active-active operation is not the same thing as the always-active feature. The always-active feature

is used to simplify the topology of high-availability FWLB configurations, and can be used in an

active-active configuration.

Figure 10 shows an example of ServerIron ADX chassis configured for high-availability FWLB.
