BAD-TRAFFIC IP Proto 103 (PIM)

[Everett Littles <bigtony () mac com>]

I am getting a load of the following errors:
<x-tad-bigger>BAD-TRAFFIC IP Proto 103 (PIM)

</x-tad-bigger>I've had about 10 in the past 15 minutes.  The snort alert description states that this is a Cisco IOS attack.  Should I be worried about this? I am not running a Cisco router.  Do I need to report this?

Thanks.
