Strange network traffic??

[Dragoncrest]

	Hi all.  Just a few weeks back I started noticing this traffic showing up 
on my lan and I have no idea how to explain it.  Using trafshow I get the 
from address as my router gateway for our connection coming in from our 
provider, and destination as OSPF-ALL.MCAST.NET, the protocol is OSPF, and 
it's only sending about 80 bytes of data every 30 seconds to a minute or 
so.  It's obviously not internal network traffic as source and destination 
are not internal, yet these show up on my machine when I'm monitoring the 
network.  Any suggestions, ideas, or thoughts as to what the heck this is??
