I have three servers with IP addresses (10.15.23.23, 10.15.23.24, 10.15.23.25). Server 1 and Server 2 have Tomcat installed and are configured as a cluster listening on a multicast IP address (237.24.2.100). I'm seeing UDP traffic between servers 1 and 2 on the 3rd server which is a windows machine. That is when I run wireshark on the 3rd server, I see 1 and 2 talking. Is this okay? Will this cause any issues? I'm not an expert in networking.
Please help.
