The idea was trying to discover switches/bridges/translational bridges which would be transparent to your L3 traceroute.
Thing is L3 traceroute relies on IP implementing error signaling using ICMP. L2 does not implement such a service, therefore generic L2 traceroute should be imho very difficult to achieve. But, if you are facing specific hardware, you can try to discover L2 devices through specific tools and features (see Cisco tool mentionned before), layer 2 discovery protocols such as CDP or analysing specific layer 2 signaling protocols (STP, VTP, etc.) if you can access them. -- http://sid.rstack.org/ PGP KeyID: 157E98EE FingerPrint: FA62226DA9E72FA8AECAA240008B480E157E98EE
