and one more point - the same loop prevention technique may be employed at your provider's routers (juniper by default does not announce routes learned from ASn to the peers in the same ASn). Solution: http://www.juniper.net/techpubs/software/junos/junos94/swconfig-routing/disabling-suppression-of-route-advertisements.html -- In theory, there is no difference between theory and practice.
