Deploy Wide Area Bonjour on Cisco SD-Access Networks

About Wide Area Bonjour on Cisco SD-Access Networks

The Cisco Wide Area Bonjour application supports various types of Cisco SD-Access wired and wireless LAN network deployment models. This chapter provides step-by-step instructions to implement global service filter policies in the Cisco Wide Area Bonjour application, enabling network-wide service routing functions for virtual network environments, without extending the Layer 2 flood boundary.

Cisco SD-Access LAN and Wireless Fabric Mode

This section provides step-by-step global configuration policy guidelines to enable Wide Area Bonjour between Fabric-Edge LAN switches providing Bonjour services, such as wired printers to remotely connected wireless users connected over Fabric-enabled wireless networks.

The following figure shows a reference network topology for Cisco SD-Access LAN and Fabric mode wireless networks with Bonjour source and receiver in virtual network environments.

Create Service Filters for Cisco SD-Access LAN and Wireless Fabric Mode

This section lists the general steps to implement global service filters, which permit the Cisco Wide Area Bonjour application to dynamically discover and distribute service information between trusted Cisco Catalyst SDG agent switches across IP networks.

Procedure

Step 1

Navigate to the Configuration tab in the Cisco Wide Area Bonjour application.

Step 2

From the sidebar, select the subdomain for which you want to create the service filter.

Step 3

Ensure that the Service Filter box is checked.

Step 4

Click the service filter icon from the topology to view a list of the service filters for the selected domain.

You can also manually edit existing service filters from this list.

Step 5

Click Create Service Filter.

Step 6

From the Network Mode drop-down list, choose Traditional (the default mode).

Step 7

Enter a unique name for the service filter.

Step 8

(Optional) Enter a description for the service filter.

Step 9

Select one or more service types to permit announcements and queries.

Step 10

Enable or disable service filters after creating them. By default, the service filters are enabled.

Configure Source SDG Agents in Cisco SD-Access LAN and Wireless Fabric Mode

This section lists the additional configuration steps to enable discovering wired printer sources from the LAN Fabric-Edge Switch-1 in an SDG agent role. The wired printer can be discovered by remotely connected wireless users from the Fabric-Edge LAN Switch-2 in an SDG agent role.

A unidirectional service filter allows network-wide service discovery for operation and management purposes. However, the services can't be distributed across an IP network unless you configure a query SDG agent. For steps to configure a query SDG agent, see Configure Query SDG Agents for Cisco SD-Access LAN and Wireless Fabric Mode.
