Question 17

On the Alcatel-Lucent 7750 SR, which of the following statements about MP-BGP used for a VPRN is TRUE?

Routes from different customers with the same IPv4 address prefix are treated as equivalent by MP-BGP.

MP-BGP will advertise routes to other BGP sessions on the same PE without the need of policies.

The multi-protocol nature of MP-BGP allows VPRN routes to be converted into IPv4 routes in the provider core network.

MP-BGP is an enhanced version of BGP that can carry customer route prefixes for multiple VPRNs.

Question 18

Click the exhibit. This output is from router R4. Service 333 is a VPLS. Why might the peer 10.10.10.1 have the same value for IngLbl and EgrLbl?

The labels are of local significance only, so other routers can use the same value.

10.10.10.1 has yet to send its own unique label.

Router R4 is using the same tunnel to send and receive to 10.10.10.1.

The service on 10.10.10.1 is down, so it is rejecting packets.
