Prerequisites for Cisco DNA Service for Bonjour over EVPN VXLAN Layer 3 Overlay Networks
This section provides the list of prerequisites for a Cisco Catalyst leaf switch that needs to be deployed in SDG Agent mode.:
-
Ensure that you successfully configure and operate the BGP EVPN VXLAN overlay networks on the Cisco Catalyst devices before you configure Cisco Local Area and Wide Area Bonjour for LAN and WLAN networks.
-
Verify that the targeted leaf switch is supported in SDG Agent and the Layer 2 access switch is supported in Service-Peer mode. See Supported Platforms for more information.
-
Verify that the targeted SDG Agent leaf switch, Service-Peer switch and Service-Peer wireless controller (WLC) run on the minimum required Cisco IOS XE software version.
-
Ensure that the SDG Agent leaf switch, Service-Peer switch, and Service-Peer WLC run on a valid Cisco DNA Advantage license.
-
In a multilayer network with Layer 2 unicast service-routing between an SDG Agent leaf switch in distribution layer and Service-Peer, ensure that the connection is through a Layer 2 trunk in static mode.
-
Ensure that the Cisco DNA Center has IP connectivity with the SDG Agent leaf switch in either the underlay or overlay network.
-
Ensure that the SDG Agent leaf switch has IP connectivity with the Service-Peer switch and Service-Peer WLC in the same IPv4 subnet when the traffic is globally routed through the management VLAN.
-
Verify that wireless AP multicast is configured in the underlay network and Cisco Wireless APs have successfully joined the AP multicast group announced by the WLC.
Note |
The leaf switch can also enable unicast-based service-routing with a downstream Layer 2 access switch and Catalyst 9800 Series WLC. |
