I'm seeing that 224.0.0.9 is detected as IGMPv2 by wireshark and not RIP as it shouold be .

i checked the IGMPv2 RFC but it never indicates that this 224.0.0.9 is used by the protocol .Only RIP does .

What is the protocol field value in your IP header?

It's not the destination address that defines this packet as IGMP, it's the IP protocol number which identifies this as IGMP. RIP(2) is running over UDP, a different IP protocol.
