Ive noticed something odd about VT Tunnels. There does not seem to be an easy way to view what VTs are contained in a given tunnel. The details on the Tunnel just shows the path and the STS used but not whats inside it.
Also, when deleting a tunnel there is a message that says "deleting tunnels with circuits in it will affect traffic" or something to that effect. If you click ok on an empty tunnel, the deletion goes thru without incident.
If you click ok on a tunnel with existing VTs in it, you get a sanity check failed saying that there are existing circuits in the tunnel.
Wouldnt it make more sense for the sanity check to be done up front and telling the provisioner that there is or isnt circuits in the tunnel beforehand? Either way, it would certainly be nice if the contained VTs in a tunnel could be viewed beforehand.
