Hi
This should (?) already be covered by http://savannah.nongnu.org/bugs/?38803
With the reservation that there was some confusion regarding multiple
interfaces so maybe this solution is more correct, and broadcast ping
should be solved in a similar manner?

I was trying to ping a multicast address on a LWIP-Stack (using the master
code) with LWIP_MULTICAST_PING enabled.
I could see in Wireshark that lwip send an ICMP-echo which linux ping did

I am running lwip version 1.41 on a Linux server(red hat release 6.4). I am

Bob, thank you for your informations.
Yes the router sends an IGMP queries, and all the multicast host replies.

May be after a good reset of switch, pc and router.
And the messages are not more broadcasted, just send to the right devices.

Hello,
I'm working with lwip and freertos on STM32.
I did a task based on sockets which is listening on multicast address.
It works when I send a multicast message from PC, and my board answer. So
far so good.
But I took a wireshark capture and lwip doesn't send an IGMP join group.

Thanks for the response!
I did this, and now I can subscribe, but my implementation is ignoring IGMP
membership queries from the router and so gets dropped after a couple of
minutes. Is there something I'm supposed to do to get this to work, or is my

You have to have the IGMP flag set somewhere.

Unfortunately, I can't help you much there, as I don't really use IGMP...
However, your code does seem correct. Do other packets have trailing zeros?
