Within a territory, either all Brokers use SSL or no Brokers use SSL. You cannot mix SSL-enabled Broker Servers and non-SSL-enabled Broker Servers in the same territory. Similarly, encryption, when enabled, is enabled for all connections between Brokers in the territory. You cannot selectively enable encryption between certain Brokers.

When the Broker Servers in a territory are SSL-enabled, you can use an access control list (ACL) to identify which Brokers are authorized members of the territory. Brokers that are not listed in the ACL, are not allowed to join or participate in the territory.

For more information about securing a territory, see Territory ACLs.
