A.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.

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

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

D.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.

A.ample Policy should be applied as an export policy on all PEs connected to sites of Customer 1

B.ample Policy should be applied as an export policy on the PE connected to the main site of Customer
1

C.ample Policy 3 should be applied as an export policy on both PEs connected to the main site of Customer 1 and the main site of Customer 2

D.ample Policy should be applied as an export policy on both PEs connected to the main site of Customer 1 and the main site of Customer 2

E.ample Policy 3 should be applied as an export policy on the PE connected to the main site of Customer
