[Linux-cluster] multicast howto

[Wolfgang Pauli]

Hi,

I am trying to setup gfs on a cluster that spans over two subnets. dream is a 
node with to interefaces, one on each subnet. I thought the below setup 
should work (taken from http://gfs.wikidev.net/Installation ). But it does 
not. Can anybody tell me what is wrong with that?

cheers,

wolfgang
