[PVE-User] Clustering without multicast

Do you have any information on how to setup a GRE tunnel?

As I am limited to two network interfaces on one of my servers. And 1 is used for communication to the outside world/cluster and the other is for san iscsi traffic.

Should you have trouble with multicast over your switchs, you can:
- use a dedicated link (easy with only 2 nodes)
- use a GRE tunnel for multicast communication.
