A legacy enterprise is using a Service Provider MPLS network to connect its head office and branches. They want to extend the existing IP CCTV network to a new branch without routing changes or IP address changes. What is the best approach?
D (EoMPLS - Ethernet over MPLS):EoMPLS allows Layer 2 extension across MPLS without IP addressing or routing changes, preserving VLANs and broadcast domains — ideal for extending CCTV networks transparently.
Other options explained:
A: GRE encapsulates Layer 3, requiring IP configurations.
B: L2TPv3 is possible but not common over MPLS SP networks.
C: VXLAN is more suited for data center overlays, not WAN/MPLS integration.
