[Linux-cluster] Multicast address by CMAN

[Parvez Shaikh]

Hi all,

As per my understanding, CMAN uses cluster name to internally generate
multi-cast address. In my cluster.conf

Having a cluster with same name in a given network leads to issue and is
undesirable.

I want to know is there anyway to find if multicast address is already in
use by some other cluster, so as to avoid using name that generate same
multicast IP or for that matter configuring same multicast IP in
cluster.conf

Thanks,
Parvez
