Sure. Exchanges and queues can either be durable or transient - the 
latter type do not survive broker restarts (but are slightly less 
expensive to create). The HTTP API (and hence rabbitmqadmin) defaults to 
declaring transient exchanges / queues (hmm, maybe it shouldn't - but it 
does). To ask for a durable exchange:

$ rabbitmqadmin declare exchange name=xxx type=topic durable=true
