Can you please share your exact topology?

In the meantime, I'd suggest trying the spanning_forest component instead of spanning_tree.

Unfortunately, I don't see any attachment.

But I think that assertion hits when there are self loops in the topology. The spanning_tree component just doesn't handle that case.

sir could you please tell how to implement the topology given in the attached file ( half-mesh topology) and could you please tell how to run a proxy controller (1 pox controller, 1 mininet, 1 proxy controller for pox) Thanks and Regards Shalini

I'm afraid that I still can't see your topology, and I don't know what a proxy controller is. Sorry I can't be of more help!
