Hello
These are not harmful messages, the meanings of the messages are as follow:
"IIF" is input interface index and
"proto" is the protocol number
As per the logs proto is 2 which corresponds to IGMP messages. This means that you are receiving IGMP packets on an interface which is not configured for IGMP.
If these messages are overloading the log file, you can simply filter them. Please visit the below KB link:
