Route multicast traffic to specific ports

Hi,

I'm trying to route multicast from specific ip addresses to 3 ports.

The multicast traffic is used by a propreitary device that cannot register to multicast groups on my setup and I would like to route the traffic to the ports manually.

 

Since the only multicast traffic on the switch are the streams I would like to forward, it doesnt matter to me if I route all the multicast traffic on the switch to those ports.

 

Switch FW is  12.0.13.8.

 

I attempted to enable the multicast router on the target ports, Switching -> Multicast -> IGMP Snooping -> Multicast Router Configuration and enabled the 3 ports I would like the traffic to be redirected to - (see the attached screenshot) but it did not work.

 

I should mention that it did work on an older FW version - 12.0.6.7

 

Any help is appreciated,

 

Thanks!

  • Hi Yishay_me ,

     

    Running the latest firmware, yes, you're only half-way there with your tentative configuration.

     

    • Please try the following using the GUI:

    Under Switching/Multicast/IGMP Snooping/Configuration,  please disable "Exclude Mrouter Interface Mode"

    Under Switching/Multicast/IGMP Snooping/IGMP Snooping VLAN Configuration,  please disable "Exclude Mrouter Interface Mode" for the VLAN 1 (if this is the VLAN 1 you are suing on these ports)

    And like you were doing in Switching/Multicast/IGMP Snooping/Multicast Router Configuration please enable the ports 4, 6 and 8.

     

    • Alternatively (same thing) but using the CLI:

    vlan database

    no set igmp exclude-mrouter-intf 1

    vlan routing 1 1

    exit

    configure

    no set igmp exclude-mrouter-intf

    interface 1/0/4

    set igmp mrouter interface

    exit

    interface 1/0/6

    set igmp mrouter interface

    exit

    interface 1/0/8

    set igmp mrouter interface

    exit

    exit

     

    I hope this will help you!

    Regards,
