This chapter provides configuration guidelines to implement Local Area Bonjour enabling end-to-end policy-based mDNS service discovery and distribution across multilayer wired and wireless FlexConnect local-switching mode. The first hop mDNS gateway at Layer 2 access switch must be implemented in service peer mode and paired with common distribution-layer switch in SDG agent role IP gateway function to wired and wireless clients. The network-wide distributed SDG agent can be paired alternatively with the Cisco DNA Center to enable mDNS service-routing across IP core network providing mDNS service assurance, monitoring and troubleshooting.
The following figure illustrates unicast mode bonjour network environment with AirPrint capable printer and wireless user computer (macOS, Microsoft Windows, and so on.) connected to the same Ethernet switch. The network administrator implements the policy permitting additional endpoints associated to nearby location Ethernet switch to discover and use remote AirPrint capable Printer without flooding mDNS over wired and wireless networks.
