Why would Multicasting be set to go from the Nokia to the multicast network?

The title says it all.  I have 2 checkpoint firewalls that have the source as themselves and the destination as the multicast network (224.0.0.0 255.0.0.0).  Does this make any sense to anyone?  Why would this be the case?  I know nothing about the Nokias, but I'm familiar with basic firewall setup.

Those are probably discovery type protocols running.

The 224.0.0.0 multicast range is reserved for local LAN traffic.
It is used for things like router discovery, routing protocols, etc.

Thanks.  Any clues for Nokia (Checkpoint)?  I need a specific answer.

No, I don't have anything specific for you.
It all depends on how the Checkpoint is configured, what services are running, what protocols, etc.

I just found out the reason.  It is required for Checkpoint Clustering.  I haven't found a URL yet though.  This is from the network team.
