> The Link management object that represents a connection between two federated
> brokers is indexed (identified) by the remote broker's host and port. If the
> remote broker is part of a cluster, and a failover event occurs, the
> host:port used by the Link object's index may no longer exist. This prevents
> the route from being deleted.
> For example, create a cluster of two brokers using addresses 127.0.0.1:2222
> and 127.0.0.1:3333. Start a third broker, say 127.0.0.1:8888. Create a
> queue route from 127.0.0.1:2222 to an exchange on 127.0.0.1:8888. Kill the
> broker 127.0.0.1:2222. This results in a Link object that is connected to
> 127.0.0.1:3333, but reports 127.0.0.1:2222 as it's host.
