Symptom: Cisco DNA Center's Assurance app may show DNS/DHCP reachability alarms in a particular VN. Configurations sent by Cisco DNA Center may include IP SLAs for checking DHCP/DNS reachability on the fabric borders. This can cause Assurance alarms due to using an L3-handoff IP addresses as a probe's source. Users may not advertise L3-handoff subnets into the routing domain outside the fabric (there is no explicit recommendation to do this). That causes the IP SLAs to fail. Conditions: This happened in an SDA fabric where IP SLAs pushed by Csco DNA Center are using L3-handoff IP addresses as probe sources.
