You can run a multicast tester java app that bea provides to see if multicast traffic is getting to the other servers.  You might want to confirm that your firewall is not blocking multicast traffic for the IP/Port that you configured in the cluster configuration.

If your Weblogic version supports Unicast, switch from Multicast to Unicast cluster mode and forget about multicast issues.
