Tim, To be clear, NoB and M/S are mutually exclusive within the same master/slave group, but the same does not hold true for "cluster" given its ambiguity.

So (to pick a random example) if you have clusters made of M1/S1, M2/S2, and M3/S3 and wanted a NOB with connections between clusters 1 and 2 and between 2 and 3, you could configure M1, S1, M3, and S3 to each have a duplex failover networkConnectors to both M2 and S2, i.e. failover:(tcp://M2,tcp://S2). Only one node of each cluster will be active at a time, so if M3 is active, it will attempt to connect to M2 first and if S2 is active then M3 will fail over to S2 when it can't connect to M2. S3 won't be active in this example, so you'll have only a single duplex networkConnector between S2 and M3. All of your clients will need to use the failover protocol containing at least one pair of master/slave brokers to guarantee that there will be at least one broker available to the client at all times, though you could throw all 6 brokers into a single failover URI if you wanted to be able to connect to any broker in the network.
