Remove unused routes and links

Hi

I have this scenario:

Two federated qpid A and B, in different machines, with routes ( and links) between them.

Without deleting any configuration I've remove qpid B and added a qpid C.

From this moment I couldn't configure qpid C with routes between A and C because qpid A was returning an error complaining the routes between A and B.
Routes from A and B couldn't no longer be deleted because A was not finding B anymore.
I got stuck until I've reconnected B, erased all the routes and links from A to B, removed B, reconnected C and configured C.
Shouldn't it be a way of forcing the deletion of routes without one being present?

Best,
Filipe Santos
