How to configure multicast function in Ruijie AP？

1. Networking requirements
          Wireless users can receive the multicast traffic
2. Networking topology

3. Key points of configuration
     Enables multicast function on AC
     Enables multicast function on AP
     Enable unknown message broadcast function on AC
     Enables PIM protocol on core switch
4. Configuration Steps
1.Enables multicast function on AC (If it is local forwarding, the multicast function cannot be enabled on the AC)
        AC(config)#ip multicast wlan   ----->Enable wireless multicast
        AC(config)#ip igmp snooping   ----->The igmp detection function is enabled globally and must be used in conjunction with the pim protocol(It is required to enable multicast routing protocol in the core switch)
2. Enables multicast function on AP
        AC(config)#ap-config ap220-e
        AC(config-ap)#igmp snooping ----->AP enable igmp etection function
        AC(config-ap)#exit
3. Enable unknown message broadcast function on AC
       AC(config)#data-plane wireless-broadcast enable
       AC(config)#end
       AC#write
4. Enables PIM protocol on core switch
     Core(config)#ip multicast-routing  ----->enable multicast routing function
     Core(config)#interface vlan 10   
     Core(config-if-VLAN 10)#ip pim dense-mode   ----->Layer 3 interface enables PIM protocol
     Core(config-if-VLAN 10)#exit
     Core(config)#interface vlan 50
     Core(config-if-VLAN 50)#ip pim dense-mode
     Core(config-if-VLAN 50)#end
     Core#write
Note: If multicast needs to cross network segments and PIM uses sparse mode, RP needs to be configured[/strong]
5. Configuration Validation
  1. Wireless users can receive multicast messages normally by using the Wsend and Wlisten multicast software for testing.

      Note: Wlisten can only support XP system
  2. Log in AC and confirm whether multicast forwarding is generated:
      show ip igmp snooping mroute
      show ip igmp snooping group

3. Log in AP and confirm whether multicast forwarding is generated:
    show ip igmp snooping mroute
    show ip igmp snooping group
