A cluster gateway enables two clusters to exchange documents. Unlike clusters, whose constituent Brokers automatically share their document types and client groups, a cluster gateway requires an administrator to explicitly specify which document types the clusters are permitted to send and receive. Moreover, the clusters never share client group information across a gateway.

Conceptually, Broker cluster gateway is conceptually similar to a territory gateway except that multiple gateway connections are supported between two clusters. Multiple gateway connections are required to support failover in case of Broker failure or network outage as well as to support multiple redundant paths for the multisend load balancing policy.
