Which statement is true comparing L2TPv3 to EoMPLS?
A.
L2TPv3 requires OSPF routing, whereas EoMPLS does not.
B.
EoMPLS requires BGP routing, whereas L2TPv3 does not.
C.
L2TPv3 carries L2 frames inside MPLS tagged packets, whereas EoMPLS carries L2 frames inside
IPv4 packets.
D.
L2TPv3 carries L2 frames inside IPv4 packets, whereas EoMPLS carries L2 frames inside MPLS
packets.
Ethernet-over-MPLS (EoMPLS) provides a tunneling mechanism for Ethernet traffic through an
MPLS-enabled L3 core and encapsulates Ethernet protocol data units (PDUs) inside MPLS
packets (using label stacking) to forward them across the MPLS network.
Another technology that more or less achieves the result of AToM is L2TPV3. In the case of
L2TPV3 Layer 2 frames are encapsulated into an IP packet instead of a labelled MPLS packet.
