• B.Traditional BGP loop detection mechanisms are unable to detect a loop in a VPRN scenario.
• C.BGP loops are detected in a VPRN when the customer has separate sites using the same BGP autonomous system number.
• D.The Nokia 7750 SR rejects routes containing AS_PATH loops by default.

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

• A.The Alcatel-Lucent 7750 SR accepts routes containing AS_PATH loops by default.
• B.Traditional BGP loop detection mechanisms may detect a loop in the VPRN scenario, which in fact is not present.
• C.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.
• 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.

The policy shown is configured on an Nokia 7750 SR to implement an extranet VPRN between the main sites of two separate VPRNs. Route target "target:65100:2" is used for Customer 1 routes, and route target "target:65100:3" is used for Extranet routes. How should this policy be applied?

• A.The policy should be applied as an export policy on the PE connected to the main site of Customer 1.
• B.The policy should be applied as an import policy on all the PEs connected to the sites of Customer 1.
• C.The policy should be applied as an import policy on the PE connected to the main site of Customer 1.
• D.The policy should be applied as an export policy on all the PEs connected to the sites of Customer 1.
