On a FastIron Super-X, I get this message on the console from time to
time:
Debug: May 17 14:44:11 IGMP: Warning! V3 mbr, bad G-rec1, #grp=1,
G=224.0.0.251, pkt S=ip.ad.re.ss to 224.0.0.22, on v500 (phy e9/2),
igmp_size=16
It is usually the same client as far as I can see. What is the
significance of this "Warning!", and what is a "bad G-rec1"? Group
received? I only seem to pick this up in a very specific circumstance on
the network which is a little puzzling. Should I worry about it?
Jethro.
