[Linux-cluster] Configuring multicast on RHEL4

[Yan Vinogradov]

Hi all!

My understanding is RHEL4 clusters default to broadcast upon creation. 
If later on the user chooses to switch to multicast - how does the 
clustering software know what interface name is to be used for each node 
of the cluster? 'system-config-cluster' utility seems to just be using a 
hardcoded value of "eth0" regardless of the actual name of the interface.

Thank you,
Yan
