Capturing and analyzing IGMP packets

Hi,

I am wondering if Bro is able to capture and analyze IGMP packets ?

I tried to turn all filters off ("redef capture_filters = {};" at the end of
brolite-sigs.bro)

I built a very simple signature:

signature header3
{
  src-ip == 10.92.39.3
  event "Header 3"
}

When I run with this on a trace containing only IGMP traffic, nothing appends
even though there is plenty of packets with src-ip == 10.92.39.3 in the trace.

I tried running with the same config on a trace containing TCP, and there I get
the alarms.

Is there any way to get Bro to analyze IGMP packets ?

Thanks!
