Multicast question

Hi,

I have been struggling to put two hosts (one is an IBM Thinkpad T520, the other an Intel NUC) into the same cluster without success.

On a debian 8 + Proxmox 4 machine, when I run
# corosync-cmapctl -g totem.interface.0.mcastaddr
I get
Failed to initialize the cmap API. Error CS_ERR_LIBRARY

I have installed the same debian+proxmox configuration inside VMs on my MacBook running Fusion 6 and I was able to join the cluster without error while with the physical hosts mentionned above, it fails miserably. They are on an unmanaged DLink router.

I feel that as long as I don't solve the multicast issue, I will never be able to get the hosts in the same cluster.

Any idea is welcome !

Marc
