Layer 2 Control Protocols (L2CP) is a group of protocols standardized by IEEE
802.1, which are used by both Service Provider and Customer L2 Switching
Devices. The group of protocols is identified by its destination MAC address.
Each ML system allows per port behavior control over each MAC address of an
L2CP group. The following behavior types can be defined:
- Discarding of undesired L2CP frames in Service Provider-Customer
Network and vice versa, which provides full demarcation (as specified in IEEE
802.1ad standard) between Service and Customer L2 Switching devices.
- Peering (accepting and locally handling) of all L2CP frames, which
provides convergence of all L2 Switching devices into the one common
network.
- Tunneling (as specified in MEF-10), i.e. ability to forward Customer L2CP
frames through a Provider Network. The following types of tunneling are
supported: Transparent, VLAN Tagged, Tunneling by MAC.
