When I first posted this trace I was pretty sure that these packets had something to do with checkpoint firewall clusters but was unsure about the reasons for the all the zero fields. I've since been told that these packets are indeed used to keep the two members of the cluster in sync. The primary member uses the fe:00 address and the fe:01 is the secondary. The reason for all the zero fields is basically speed, they are not used so they don't need to be set.
