lwip igmp ( am i doing right? )

hallo world,

 

I try to use igmp but I'm not sure if I'm doing right. ( Since i dont have a real igmp-Sever to connect to...)

 

I use VLC to stream out data to lets say 224.0.0.0.

 

To receive data with Lwip i do this:

1st: igmp_joingroup( 224.0.0.0)

2nd: Build UDP-Connection with [ source: unknown; destination: 224.0.0.0 ]

 

But is this right? Would a real igmp behave like this?

 

I have a fixed ip for the receiving module ( 196.168.1.1)

 

So actual question:

After join-group ( 224.0.0.0). Are the packets send to 224.0.0.0 or to 196.168.1.1 ?

 

Is it clear what I'm trying to get to know?

You can use basic example design of EMAC with address swap module generated from coregen which will send and receive IGMP ping packet  request using arp -s command.
