How configure IP SLA in Cisco ASA?

ASA Dual ISP using IP SLA

  1. Create nat rules for traffic routed out of the primary and secondary interfaces.
  2. Schedule the SLA process to start immediately with a lifetime of forever.
  3. Create a track ID, the “rtr” references the SLA ID.
  4. Define a default route via the PRIMARY interface, referencing the track object.

How does Cisco IP SLA work?

IP SLA is an active method of monitoring and reliably reporting on network performance. By “active,” I refer to the fact that IP SLA will generate and actively monitor traffic continuously across the network. An IP SLA Router is capable of generating traffic and reporting on it in real time.

What is IP SLA in networking?

IP SLA (Internet Protocol Service Level Agreement) is an active computer network measurement technology that was initially developed by Cisco Systems. IP SLA is used to track network performance like latency, ping response, and jitter, it also helps us to provide service quality.

How is the ASA configured for the primary ISP?

The ASA is configured with a static route that directs all of the Internet traffic to the primary ISP. Every ten seconds, the SLA monitor process checks in order to confirm that the primary ISP gateway is reachable.

What happens when the backup route is removed from the ASA?

While the backup route is in use, the SLA monitor operation continues its attempts to reach the monitoring target. Once the target is available again, the first route is replaced in the routing table, and the backup route is removed. In the example that is used in this document, the ASA maintains two connections to the Internet.
