A customer with a dedicated Frame Relay network plans to move its circuits onto a service
provider converged MPLS network. Instead of moving to Ethernet access links right away, the
customer wants to tunnel the Frame Relay information across the converged network. In which
way is QoS information transmitted across an AToMpseudowire when tunneling Frame Relay
traffic?
A.
QoS information cannot be transported through a pseudowire and is dropped.
B.
QoS information is preserved in the Frame Relay header and encapsulated into the
pseudowire frame.
C.
QoS information is carried in a control word that is attached to the MPLS frame.
D.
QoS information is translated into ToS bits in the Ethernet header.
