[ClusterLabs] corosync in multicast mode produces lots of unicast traffic

I have a Proxmox cluster which uses Corosync as cluster engine. Corosync 
uses the "default" multicast configuration. Nevertheless, using tcpdump 
I see much more packets sent by corosync using unicast between the node 
members than multicast packets.

Is this normal behavior? If yes, please point me to some documentation. 
If no, does this mean I have some broken configuration? Everthing seems 
to work fine with my setup.
