Switch Routing Multicast Configuration

Multicast Traffic Management

Switch routing multicast configuration in Meraki networks provides administrators with comprehensive multicast traffic control capabilities, enabling efficient multicast distribution, IGMP snooping optimization, bandwidth conservation, and network performance enhancement. This functionality supports multicast group management, unknown traffic handling, IGMP query processing, multicast forwarding optimization, and network resource conservation. Multicast routing is essential for video streaming applications, software distribution systems, real-time collaboration tools, and enterprise environments requiring efficient one-to-many communication patterns.

Examples

Example-1: The example below demonstrates switch multicast routing configuration using tested YAML configuration from pipeline fixtures.

meraki:
  domains:
    - name: "!env domain"
      administrator:
        name: "!env org_admin"
      organizations:
        - name: "!env org"
          networks:
            - name: "!env network_name"
              product_types:
                - appliance
                - switch
                - wireless
                - camera
                - sensor
                - cellularGateway
              switch:
                routing_multicast:
                  default_settings:
                    flood_unknown_multicast_traffic: false
                    igmp_snooping: true
