I realize now that I have confused IGMP with EGP & friends.
Looking at /etc/protocols could have saved me from this. :)
igmp 2 IGMP # internet group management protocol
egp 8 EGP # exterior gateway protocol

The bad feelings I have with these is when reading Linux mailing
lists (far behind in the past:) where people always wondered "why
does my ISP connection always go up / keep up?" when they thought
running routed(8) would be a Bright Idea (TM). Thinking about
routing in a LAN with four machines and doing it manually must be
very demanding. :> And again see my above confusion with EGP.
OK, there's sooo much yet to learn for me ... Keep buzzing when
I do something wrong, I'm very *happy* with getting corrected. :)
