command that can display routes containing AS loops

[refresh.lsong at gmail.com (Song Li)]

Hi everyone,

I am curious about the AS loops in the AS-path. I think there should be 
a very, very few received BGP routes that contain the local AS#. But 
because such routes will be dropped and not installed in Loc-RIB, I want 
to know if there is a command that can display the dropped routes 
containing AS loops (in cisco or juniper router). Does anybody know?

Thanks!

Best!
