I m trying to see the IPV4 multicast option at the Subscribe_Event _groupe_ack message using Wireshark but the length of options is always 0 ! so I can't see the IPV4 multicast option, Although I am adding the multicast option true at the .json file. I'm running the notify/subscribe example offered by the stack. i will be thankful for any helps
