What is wrong with the configuration shown below?

A. The VPRN ID must be the same value as is used in the vrf-target command

B. The VPRN ID must be the same value as is used in the route-distinguisher command

C. The router-id command should not be used in this context

D. The vrf-target command is mandatory

E. There is nothing wrong with this configuration

An advantage of using BGP as the PE-CE protocol is that route policies are no longer required to control the exchange of routes from BGP to MP-BGP.

A. True

B. False

When an Alcatel-Lucent 7750 SR receives a BGP update containing an AS-Path loop, what is the default action?

A. The update is accepted and the route installed in the route table.

B. The update is accepted but the route will not be installed in the route table

C. The update is rejected

D. The peer session is dropped

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

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

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

C. 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.

D. 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.
