Nop it doesn't.
In your case, I'd check the network architecture and/or firewalling 
regarding multicast. You probably either have wrong iptables and/or a 
switch dropping your multicast corosync ring(s).

Also, please, as Andreas said: try to communicate with us in a more 
efficient way: more context, more informations and more output (pasted 
somewhere).

We are happy to help people, but we don't have to waste our time trying 
to understand what these exact people doesn't tell us because they are lazy.

ps: also use 'corosync-objctl' ; it's a good command to debug rings and 
configurations.

Cheers,
Florian.
