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 . ftp://mood.ateme.com/Clement/IGMPv2.jpg do you know why wireshark is seeing this ? asked 29 Apr '15, 07:21  Clement Duval |
One Answer:
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. answered 29 Apr '15, 12:35  Jaap ♦ |
What is the protocol field value in your IP header?
