MPLS

A VPLS receives a frame with the single VLAN tag 35 on the Q-in-Q SAP 1/1/1:35.*. Which of the following describes default Alcatel-Lucent 7750 SR behavior?

A.

The frame is dropped.

B.

The VLAN tag is removed, and the frame is transported over the network.

C.

The VLAN tag is kept, and the frame is transported over the network.

D.

The VLAN tag is kept, a VLAN of 0 is added, and the frame is transported over the network.

Which of the following about an E-pipe terminating on a VPLS is FALSE?

A.

The VC-IDs used between the E-pipe and VPLS must match.

B.

The E-pipe must maintain a MAC FDB in order to connect to the VPLS.

C.

The service ID of the E-pipe can be different from that of the VPLS.

D.

The service MTU of the VPLS and E-pipe must match.

A service needs to accept frames that have the following: an outer VLAN tag of 200 with an inner VLAN tag of 33; and frames that have an outer VLAN tag of 250 with an inner VLAN tag of 33. What SAP(s) need to be configured?

A.

1/1/1:200.*

B.

1/1/1:*.33

C.

1/1/1:*.*
