Which of the following about BGP loops in a VPRN environment is FALSE?

Traditional BGP loop detection mechanisms may detect a loop in the VPRN scenario, which in fact is not present.

The Alcatel-Lucent 7750 SR accepts routes containing AS_PATH loops by default.

When the CLI command "config>router>bgp# loop-detect discard-route" is used, the Alcatel-Lucent 7750 SR sends a notification to the remote peer and drops the BGP session.

In VPRN implementations where the CE-PE protocol is BGP, it is possible for separate sites of the same customer to use the same BGP autonomous system number.
