>From a technical standpoint, yes.  BGP sees a loop whenever it sees its own
AS in the path.

>From a political/personal standpoint, you need to reach out and smack the
brainchild that is prepending YOUR AS into their BGP records.  It would
serve them right to not be reached.

Just my thoughts.

Hi All,
 
If I have an external BGP connection to my neighbor, and if the neighbor is
Prepending my own AS to the routes that is sending to me, do I need to
implement the command " set routing-options autonomous-system loop to all of
my internal routers inside my AS in order to get those routes?
So far, the only way I have been able to get the routes to all my internal
routers is by applying the loop command, and do a clear BGP neighbor
soft-inbound I am running JUNOS 7.3R3.6, Is there any other way of
implementing this?
 
Thanks,
Reza
