AFAIK OSPF (Open Shortest Path First) is a protocol used by routers for determining optimal pathways through the network. The frequency suggests router advertisements: "I'm here and I route traffic to network xxx.xxx.xxx.xxx/xx". I think OSPF uses multicast (and older RIP uses ICMP??) Capturing and analyzing the packet headers would probably clear up the mystery rather quickly. I leave it to more knowledgeable list members to explain more and/or correct my ignorance :) Cheers, VS On Thu, 2003-04-17 at 22:27, Dragoncrest wrote: > Hi all.
