L2CP Tunneling for VPLS/VPWS/Hybrid (Bridge+VPWS)
L2CP tunneling provides support for tunneling Control plane frames across L2VPN.
Default Behavior
If control packets are received at the PE router on AC port (vlan tagged/untagged), corresponding AC port properties will take care of forwarding to peer PE node. These packets are encapsulated with MPLS headers and sent across the network to the remote PE router. The egress PE router receives the packet and performs MPLS decapsulation and forwards to the CE. Except for LACP, all other control packets are tunnels across the MPLS circuit.

Hybrid Port
When the incoming port is configured as Hybrid (Bridge+L2VPN), L2CP switches to peering mode. You can override this behavior with the help of L2CP configurations.
