Subject: [Snort-users] Cisco Proprietary Protocol and Snort

Hello,
My Snort keep telling me that it detect "snort_decoder: WARNING: BAD-TRAFFIC Bad IP protocol" (Sid:450,Gid:116) hourly 
which come from my Cisco Switch send Multicast Packet to the Network with its proprietary PIM protocol 
(sparse-dense-mode).
I'm curious that my Snort cannot decode Cisco PIM Protocol. So,it detect as
"WARNING: BAD-TRAFFIC Bad IP protocol" Is it possible?
