Cisco ASA Configuration Options

Select the configuration based on the ASA software version:

Important

We recommend using a route-based configuration to avoid interoperability issues and to achieve tunnel redundancy with a single Cisco ASA device.

The Cisco ASA doesn't support route-based configuration for software versions older than 9.7.1. For the best results, if the device allows it, we recommend that you upgrade to a software version that supports route-based configuration.

With policy-based configuration, you can configure only a single tunnel between the Cisco ASA and the Dynamic Routing Gateway (DRG).
