> The Well Known Addresses (WKA) feature is a mechanism that allows cluster members to discover and join a cluster using unicast instead of multicast. WKA is most often used when multicast networking is undesirable or unavailable in an environment, or when an environment is not properly configured to support multicast. All cluster multicast communication is disabled if WKA is enabled.
