Is it possible to Cluster App Servers on different subnets

[dhobson]

Can it be done? The machines are in the same company and accessible to every application from every port, etc. Is there docs for this? I've been searching with no luck.

I asume your network routers will have to pass the IP multicast traffic from one subnet to the other in order to let JGroups work.

Or you can use unicast packets, but that will increase your traffic.

Anyone knows more? We are also interested in this possibility.

Yes, switches and routers have to be enabled to forward multicasts, then this should be no problem
