Design question / What would you recommend and why: L2 tunneling over L3

L2 tunneling over L3. It's better to use VPLS. Other VPN cannot implement.

Thank you very much!

In this case I'm going to investigate LDP VPLS.

Excerpt out of S2750EI&S5700 Series Ethernet Switches Configuration Guide - VPN

Traditional MPLS L2VPNs, such as the virtual leased lines (VLLs), can provide P2P
services but not P2MP services over a public network.

MPLS L3VPNs can provide P2MP services on the precondition that PEs keep routes
destined for end users. This implementation requires high routing performance of PEs.

To solve the preceding problems, VPLS, an MPLS-based Ethernet technology, is introduced.

Like Ethernet, VPLS supports P2MP communication.

VPLS is a Layer 2 label switching technology. From the perspective of users, the entire
MPLS IP backbone network is a Layer 2 switching device. PEs do not need to keep routes
destined for end users.
