How to configure service broker with availability groups?
Configure the route as follows: Set ADDRESS to the listener IP address of availability group that hosts the service database. Set PORT to the port that you specified in the Service Broker endpoint of each of the remote SQL Server instances. The following example creates a route named RouteToTargetService for the ISBNLookupRequestService service.
How are SSB connections severed during availability group failover?
Incoming (SSB) connections are severed during a availability group failover and those connections use the listener IP address which directs connections to the new primary replica. New incoming SSB connections, established through the listener, will go to the new replica.
What happens if SQL server fails to connect to service broker?

How to create a service broker in MSDB?
Ensure that msdb contains either an AutoCreatedLocal route or a route to the specific service. By default, each user database, including msdb, contains the route AutoCreatedLocal. This route matches any service name and broker instance and specifies that the message should be delivered within the current instance.
How are messages fetched from a service broker?
Every service has a queue where the messages are placed until they are processed. The messages in the queues can be fetched using the Transact-SQL RECEIVE command or by the activation procedure that will be called whenever the message arrives in the queue.
