I am not sure you need to detect the identity of currently attached link for quick
configuration either. For example, considering the CPL as the link identity, you don't 
need to detect the identity of currently attached link (the COMPLETE prefix list)
to ascertain the validity of the existing IP configuration or to quickly re-configure 
yourself. You only need one prefix - right? So, making "detecting the identity of 
the currently attached link" part of the goal is kinda misleading.
