Question 1

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?

B : The MAC addresses for the l-VPLS will age out immediately following the remote-age out of the backbonemacs of the B-VPLS

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