A customer has this wireless design:
• two Cisco Catalyst 9800 Series wireless controllers that are configured in a high-availability SSO cluster to manage the APs in a local office network
• 100 APs in local mode that are registered to the high-availability cluster
• one Catalyst 9800 Series wireless controller that is deployed as an anchor in a DMZ
• a CAPWAP tunnel in UP state between the high-availability cluster and the anchor WLC
The customer wants the anchored traffic to remain up if a single WLC in the high-availability cluster fails. How must this requirement be incorporated into the design?
