LS1028 switch can not route multicast frame which ip is 239.3.3.1

Hi, I'm working on LS1028 board as a switch; By the following switch configuration, i successed configured the ls1028 as a switch.

    ifconfig eno2 up          

    ifconfig swp0 up          

    ifconfig swp1 up

    ifconfig swp2 up

    ifconfig swp3 up

    brctl addbr br0             

    brctl addif br0 swp0

    brctl addif br0 swp1

    brctl addif br0 swp2

    brctl addif br0 swp3

    ifconfig br0 up            

Here I made three tests;

1.  Unicast  test. For example ,PC1(192.168.0.220) send a udp frame to  PC2(192.168.0.110) through ls1028 switch. The unicast frame can route successfully.

2. multicast test(ip from 224.0.0.0~ 224.0.0.225). successed;

3.multicast test(ip from 239.0.0.0~239.255.255.255) failed.

Then I tried to test other multicast ip, it failed either. It seems the switch can only support muticast ip from 224.0.0.0~ 224.0.0.225 for routing.

Does anyone know how to fix it in order to fit all multicast ip?

Hello xinliwang,

I also meet the same issue like yours, Have you fixed it and route multicast frame sucessfully for other  multicast group .i.e ip from 239.0.0.0~239.255.255.255?

 

Thanks a lot!

Hi, @hustdj 

Can you tell me which kernel version you use? I haven't solved it on LSDK20.04 but it works on other versions.

Hi ,xinliwang,

Thanks for your quick response, the kernel version I use is Linux-5.4.3(should also be LSDK20.04,right?), and which kernel version you using works?

Hi, @hustdj 

I use the real time edge 2.2 version and it works.
