Probe: EVPN VXLAN Type-5 Route Validation

The EVPN VXLAN Type-5 route validation probe validates the EVPN Type 5 routes on every leaf. The collected data is matched against the graph data to ascertain any missing routes on any system.

You can configure the following parameters:

• Probe Label: Name to identify the probe.
• Anomaly Time Window : Average period duration for interface counters.
• Anomaly Threshold (in %): If routes are missing for more than or equal to percentage of Anomaly Time Window, an anomaly is raised. If Anomaly Time Window ATW, and Anomaly Threshold is AT. It calculates Z = (ATW * AT)/100 in seconds. E.g. If ATW = 20 seconds, AT = 5%, then Z = (20 * 5)/100 = 1 second. When the route is in Missing state for Z seconds from total ATW duration, anomaly is raised.
• Collection period: All these probes are polling-based so they have a polling period.

The route labels include the following:

• Expected: This route is expected on the device as per service defined.
• Missing: This route is missing on the device when compared to the expected route set.
• Unexpected: There are no expectations rendered (by AOS) for this route.

If this probe is enabled it monitors all virtual networks from all devices. It does not provide the “monitored VN list” configuration option like the VXLAN Type-3 probe does.

Note:

Auto-enabling the EVPN VXLAN Route Summary analytics dashboard enables the EVPN VXLAN Type-3 Route Validation and EVPN Flood List Validation probes automatically (but not the EVPN VXLAN Type-5 Route Validation probe). See Configuring Auto-Enabled Dashboards<configure_dashboard> for information about enabling the dashboard.
