Technical Tip: Route selection for SDWAN healthcheck probes

This article describes that in some scenarios, the health check probes might choose an unexpected gateway resulting in probe failure.

The requirement is to route health-check probe packets via different routers.

In this example, server1 and sever2 are used as a destination for Performance SLA health-check probes.

Note:

In this case, 'named routes' cannot be used.

The following configuration will result in the same routing table, but routes defined by address objects will not be used for Performance SLA health-check probes:
