Question 5

If the max remote-age timer of a B-VPLS is reached, what happens to the remotely learned MAC addresses in the l-VPLS service?

AThere is no effect. The MAC addresses for the l-VPLS age out independently of the aging of B-VPLS addresses.

BThe MAC addresses for the l-VPLS will age out immediately following the remote-age out of the backbone-macs of the B-VPLS.

CBy default, the remote-age timer of the B-VPLS is configured to 0 and addresses do not age out. The l-VPLS uses its own timer.

DThe same timer is used for B-VPLS and l-VPLS addresses on the node.

Answer : B

Question 6

Click on the exhibit below.

Assume there are two VPLS services configured on the MDU. How could load-balancing be achieved when using Active/Standby pseudowires?

AThis cannot be done.

BEach VPLS will use the same pair of SDP's with the same endpoint configured with the option 'load-balancing 2'.

CEach VPLS will need their own pair of spoke-SDP's configured. The spoke-sdp's that are to be active should be configured with the option 'precedence primary'.

DUnder the end-point configuration, enable load-balancing 2 and the MDU will load balance automatically.
